Introduction:
Ocean acidification is when the ocean 's pH is downsized. Ever since the industrial revolution, CO2 (carbon dioxide) has increased in the earth 's atmosphere, and much has been absorbed by the oceans, which has made a very large increase in the ocean 's acidity, when carbon dioxide is absorbed into the water, it dissolves forming carbonic acid, which is a factor that take a large part in the acidity raising, because of this, according to National Geography it has been proven that marine animals are having birth defects because of this, and because of the high acidification the acid comes down on the shells (the home) of an animal and dissolves it, causing …show more content…

Hypothesis: If a pollutant such as oil is added to an aquatic environment, then the pH is more likely to be affected when sand is …show more content…

in this one, there is pollution (oil) in the water, and after the universal indicator was inserted there was just a little slight change in color, the color was like how it was in the first bottle, but this one had pollution (oil) in it bottle with half oil, salt water, and sand on bottom… this one as shown above it is very noticeable, it is easy to see the pollution (oil) on the top the sand on the bottom and the bold blue color in the middle, indicating that the the pH level had changed the most bottle with salt water and sand.. As depicted in this picture the second bottle, a slight change occurred and it was noticeable, when sand is present bottle with salt water… it is clear to see that the water only changed a slight, after the indicator was put

Second trial/after 48 hours

from left to right: bottle with salt water... the color changed a slight bottle with salt water and sand...the pH has changed a little more since the sand is present, so the change in color is

Turnip Peroxidase Lab Report

As had doing the baseline prior to changing the pH with a drastic qualitative and quantitative data change, seeing no color change and slope in the graph was concerning. However as multiple trials were completed and results were compared to other classmates, more confidence arose in the results as the numerous trials with similar results ensured validity. If there were things that could have been done differently, more precision and caution would have been taken whilst doing the lab; for example: re-reading the lab before beginning and taking time while measuring out solutions. The experiment had a few errors due to human error as well as random ones. For example, in one trial, distilled water was gathered through the hydrogen peroxide pipetter, creating a chance of error due to the cross-contamination of solutions.

These color changes indicate a chemical change, which show that a reaction had occurred. In the first step when o-vanillin and p-toludine, imine was formed. The color change from green to orange suggests that imine appears as orange colored. In the second step, the addition of sodium borohydride reduced the imine into another derivative, which was yellowish lime color. The solution turned clear when acids and anhydrides was added, which indicated the precipitate were dissolved.

Gobstoppers Will Not Change In Color Over Time Of The Experiment

948 Words | 4 Pages

The data both supports and disproves the hypothesis, which was “The gobstoppers will not change in color nor will the liquid change color over time of the experiment in the different liquids”. This is because for both the Sprite and water the liquid changed in color, along with the gobstoppers within them. The gobstoppers either got lighter in color or changed in color, and the liquid changed into the original color of the gobstoppers, or something close. For Sprite trial 1 the liquid color for red went from clear, to pinkish, to red, back to pinkish, then to light orange, and finally ending with orange. For Sprite trial 2 it went from red to orange.

Charles River Lab Report

The average diversity of location A was 1.89, location B was 2.08, and C was 1.92. However, location B may have inaccurate data. On 3 out of the 5 rocks, it was impossible to measure the diversity, because a lack of species on the rock caused the denominator of the symposia’s diversity index to be 0, leading to the reading of NA, as it is not possible to divide by 0. That meant only 2 measurements could be averaged for location B, possibly leading to inaccurate results, which would explain the spike in diversity at that location. Upon further analysis of the water collected in the follow up lab, it was also discovered that water pH and salinity did not change as we went downstream either.

Each sample had quite a different value for hardness, causing a high standard deviation and more spread-out results. Because of this, the other factors were relied on heavily to distinguish between the different waters because of the lack of similarity. Although B1 and C1 can be definitively identified, A1 could also be predicted using the components within the

The water was a light yellowish-green, and the grass was mostly light green, but a few strands were dark green. The third eyeball observation that my partner and I did was on 12/14/2017. The variable jar was almost completely black and dark green, with a few light color strands of grass. The control jar’s only difference that I could detemen through an eyeball observation, was the amount of water, which had decreased and the smell had started to become more

Ocean Acidification Formal Laboratory Write-Up Background: Around the coast of Ischia Island, the water is being saturated with carbon dioxide. Chalk at the bottom of these waters is being boiled by nearby volcano, Mount Vesuvious, thus creating streams of bubbles coming u to the surface. With the chalk coming up to the surface, it is acidifying the water around it. This ocean acidification can cause tiny sea creatures, which normally absorb carbon dioxide, to be exposed to too much carbon dioxide that will in turn have a chain reaction effect in the food chain.

Acids are proton donors in chemical reactions which increase the number of hydrogen ions in a solution while bases are proton acceptors in reactions which reduce the number of hydrogen ions in a solution. Therefore, an acidic solution has more hydrogen ions than a basic solution; and basic solution has more hydroxide ions than an acidic solution. Acid substances taste sour. They have a pH lower than 7 and turns blue litmus paper into red. Meanwhile, bases are slippery and taste bitter.

Issue Of Ocean Acidification

811 Words | 4 Pages

The issue of Ocean acidification is the direct effect of the rising levels of carbon dioxide in the ocean as well as the atmosphere. With the rise of carbon in the ocean, the pH level, which determines the amount of ocean that is acid. The root of the problem has been occurring since the 1830’s. In history, this has occurred once and that happened over 56 million years ago and the sources are unknown. This recent occurrence started due to the introduction of the Industrial Revolution.

by Brett Garling from the Mission Blue Sylvia Earle Alliance, states that factory farming contributes to the sea temperature rising and ocean acidification because the rising of atmospheric temperature is also rising global ocean temperatures, that leads to the widespread of coral bleaching. He says this is a problem because bleaching slows down coral growth which makes them vulnerable to catch a disease, and later leads to large-scale reef die-off(Garling). Also Garling states that a “greater concentration of carbon dioxide in the atmosphere is increasing the acidity of the global ocean,handicapping the extensive roster of marine organisms that build shells or

Ocean Acidification Essay

861 Words | 4 Pages

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
