Ocean Acidification Lab Report

1851 Words8 Pages

Background: In Ischia Island the water around the island has been acidified for millions of years because of Mt. Vesuvius. This dormant volcano is melting chalk in the sea floor, which releases carbon dioxide into the water acidifying it. This acidification is devastating the life around the island and is still being acidified by the continuous release of CO2. We can use this as an example of what our world might look like if we continue to release carbon dioxide emissions through things such as burning fossil fuels and reducing the carbon banks such by things like deforestation.
In the first part of this lab we will blow CO2 from our breath through a straw. When the gas comes in contact with the water it will slowly begin to acidify it. …show more content…

The shell that was exposed to the vinegar will have a weaker shell because high levels of acid dissolve the shell. Some sources of carbon dioxide are respiration, smog, pollution, and fossil fuels. The one that impacts the ocean most would be the burning of fossil fuels.
In the Ocean Acidification lab, calcium in the water combines with the carbon dioxide from the breath creating carbonic acid. This acid affects shells like the shell lab. Since the shells are made of calcium carbonate the carbonic acid acts like a corrosive and dissolves the shell …show more content…

Once the 24-hour period has passed then you will extract the shells from the vinegar beaker and record the mass of those shells and the shells that were not exposed to the vinegar. Record all data and observations on the chart labeling the vinegar shells “experimental” and the other two “control”. Then you will pour 100 ml of vinegar into a 500 ml beaker and 100 ml of salt water in the other 500 ml beaker. Set the timer to 30 minutes and drop one “control” and one “experimental” shell to each beaker at the same time. In your data table you will record the observations of what is happens to the shells while they are exposed to vinegar and the salt water every 5 minutes. Once the 30 minutes are up you will take the four shells out simultaneously with the spoons and place them on a paper towel then proceed to record the masses for all four shells. Ultimately you will test the strength of each shell by dropping a textbook from a one-meter vertical distance on the shell then record all

The purpose of the experiment was to determine what happened during osmosis and diffusion across membranes by using a fresh hen’s egg. During the first step, the egg was put into the vinegar. The shell of the egg became soft and started to fall off by small pieces. The reason of the vinegar was able to remove the calcium shell was that the acetic acid in the vinegar could react and dissolve the calcium. The formula for this reaction was CaCO3 + CH3COOH –> Ca + H2O + CO2.

Castello Argonese, a tiny island in the Tyrrhenian Sea gives us an enlightening glimpse of Earth in 2100. Chapter six of the book The Sixth Extinction by Elizabeth Kolbert, is solely devoted to her experience in these waters where the vents on the sea floor bubbled up almost 100% carbon dioxide. She talks about the consequences of constantly burning fossil fuels to add about 365 billion metric tons of carbon into the atmosphere and how it could lead to our own demise. The thing about carbon dioxide is that the moment it interacts with water, it becomes an acid which can be deadly to the animals living in these oceans obviously, but also to organisms above sea which includes humans. Elizabeth Kolbert wants us to understand that our actions have tragic consequences and we too will be part of that tragedy if we don’t stop now.

The eggs were placed in the solutions, charting the change in weight after 15, 30 and 45 minutes; handling the eggs carefully each time and wiping off any excess water to avoid a misread by the scale. It is necessary to remove the egg and weigh individually each time to get the most accurate results. After the experiment was done, the eggs were placed back in their containers and the solution discarded of. It is imperative not to put the solution back in the containers.

Carbon dioxide is a natural component of Earth’s atmosphere and has an important role in maintaining a livable life on the planet. All animals, including humans, make carbon dioxide when they breathe out. This experiment can be used to teach two things: it is an example of a chemical reaction and it shows how carbon dioxide builds up in water. Bromothymol blue is a chemical indicator that is used to find acids and bases. It is mostly used to show the pH of fish tanks and pools, measuring from 6.0 (yellow color) to 7.6 (green to blue).

Ocean acidification may not be noticeable to you when you dive in the water but to marine organisms it is having a huge affect. So lets clarify what ocean acidification is. • Ocean acidification is caused through the transfer of carbon dioxide between the atmosphere and the ocean. • Research shows that over the past 250 years the amount of carbon dioxide in the earths atmosphere has increased approximately 40%. ocean has absorbed one third of this carbon dioxide which has been caused due to human usages of fossil fuels and deforestation.

Procedure The aim of this experiment was to determine how variations in the amounts of calcium carbonate would affect the amount of carbon dioxide produced within the time frame of one minute. By measuring the amount of carbon dioxide produced, the changes in the rate of reaction could also be determined. By the end of the minute, the more carbon dioxide was produced, the faster the rate of reaction. Throughout the minute, the flask containing hydrochloric acid and calcium carbonate was swirled around in continuous, circular motions.

Pteropods are eaten by creatures varying tiny krill whales, to Pacific salmon. The picture to the right shows the projected effect on the pteropods in 2100, after only 45 days. The ocean will be greatly acidified and will have the potential to quickly dissolve the shells of certain creatures. Shellfish are also greatly affected by ocean acidification. In recent past years, there have been complete failures in aquacultural facilities and ecosystems on the West Coast.

Introduction Pollution has been around since Ancient Rome and is described as the contamination of our natural environment that is caused by chemicals and gas (Stromberg). Because of pollution in the air, more damaging consequences such as the formation of acid rain are triggered. The largest contributors to pollution are humans through industrial factories that expel foreign chemicals into the atmosphere and cause the formation of acid rain. This topic was chosen to explore the effect of man-made acid rain as a result of pollution in the air on plants, human health, and much more. The effect of pH on oxygen (O2) consumption and carbon dioxide (CO2) production is worthy of investigation because human-caused acid rain is at large at many countries and may give clarity to other events that acid rain triggers.

The effects on corals, already highly sensitive to their environment, are particularly concerning, since one part of all marine species depend on coral reefs for homes, nurseries, feeding grounds and spawning sites. This equates to nine million marine species, including four thousand species of fish. ocean forecasts the mass extinction of corals in both tropical and cold waters this century, if carbon emissions growth continues unchecked. How will ocean acidification affect

Ever since the industrial revolution commenced, around one third of the carbon dioxide released by human interference has been absorbed by the ocean, which is one of the reasons of the drastic change in climate as well. Without the ocean absorbing carbon dioxide, the carbon dioxide n the atmosphere would be drastically higher, with possibly increasing the levels of climate change. The point of the research is to see how will the pH affect the organisms in the marine ecosystem and does carbonation affect an organism’s mass and form. Many organisms that are part of the marine food chain are going to be affected by ocean acidification due the levels of acidity deteriorating the calcium carbonate within the animal. It turns out

Decline of species can cause a declining slope for the food chain regulation, predators will have no prey and will eventually starve. Species help regulate the ecosystem and a decline in species can lead to a decline or reproduction in the ecosystem. To avoid the effects of acid rain, an implementation to reduce consumption of fossil fuels should be administered. To reduce the effects of acid rain, there must be a reduction on the amount of pollutants we directly emit into the air. Air pollution is the root cause of acid rain, and with power plants releasing massive amounts of sulfur dioxide and nitrogen oxides when fossil fuels are burned, we are adding more flame to the effects of acid rain.
