The last test was called the Acidity test. The Acidity test gives us the alkalinity and acid of a stream. On the Ph scale it goes from 0 to 14. A stream with a great abundance of life will probably have a reading of 7 on the scale( which is near neutral). Here are the results from some of the tests.
Holly Weiss SC-131 Unit 7 Acidosis and Alkalosis Assignment The normal pH value for the body fluids is between pH 7.35 and 7.45. When the pH value of body fluids is below 7.35, the condition is called acidosis, and when the pH is above 7.45, it is called alkalosis. Respiratory acidosis is a condition that occurs when the lungs cannot remove all of the carbon dioxide the body produces.
AP Chemistry Semester 1 Final Review 2016 Basics of Chemistry: Name the following compounds BO3 H2S NaOH OF8 PCl6 HNO3 HgNO2 Write the formula for each compound Pentaboron triselenide Sulfuric Acid Carbon Monoxide Lithium Chloride How many moles are in 58.6 g of AgNO3 How many grams are in 2.5 moles of Cl2
I organized four different tests; pH paper, alkalinity tests, the number of rocks neutralizing acid, and the number of rocks that don’t neutralize acid. The average for pH paper was seven. The pH is the numeric scale used to specify the acidity or alkalinity of an aqueous solution. The pH scale measures acidity and alkalinity. the pH scale goes from zero, which is an acid reading, to fourteen, which is an alkaline reading.
Based on your class results is there a correlation between the strength of the acid and the amount of heat given off when it reacts with a base? a) Compare the values of the heats of neutralization for the reactions of each acid with either sodium hydroxide (NaOH) or aqueous ammonia (NH₃). Can you make any correlation between the quantities of the heat given off and the fact that sodium hydroxide is a stronger base than ammonia (NH₃)? A negative ΔH indicates a process giving off heat, making it exothermic.
One test conducted was the measure of nitrate in the water. If there is too much nitrate it grows algae which is then eaten by bacteria, and can cause Eutrophication. Another test was done to determine the amount of BOD, which shows how much dissolved oxygen is needed by Aerobic bacteria in order to break down material. Ph is responsible for how acidic or basic the water is. If a body of water has a high ph it can be unsuitable for aquatic life.
OH- ions tend to make substances basic, and H+ ions make compounds more acidic1. Additionally, this pH test affirmed that sodium hydroxide and hydrochloric acid testing were not necessary in assessing the compound’s
An excellent pH level for a stream is 7. One above or one below that on the pH scale is considered still to be good. If the pH of the stream is anything but 6,7,8 the stream is considered to have a poor pH level. Adult fish start dying around the 3 range on the pH scale. Acidic water reduces the amount of oxygen and sodium are found in fishes.
An acid is a ionic compound with hydrogen as the cation and turns litmus paper red. A base is slippery, bitter and turns blue on litmus paper. We tested HCl, HC2H2O2 and NaOH and found using a variety of indicators that both HCl and HC2H2O2 are acids and NaOH is a base. We also tested HCl and acetic acid on Zinc, Magnesium, iron and Copper to find that Zinc created a spark with HCl, Magnesium fizzed a little, Iron created bubbles with HCl and copper did nothing. * “An acid is any chemical compound which when dissolved in water gives a solution with a hydrogen ion activity greater than in pure water.
Acid and base balance of body is normally strongly controlled, keeping the arterial blood pH between 7.38 and 7.42. Acid and base is also important in human homeostasis regarding the appropriate balance between acids and bases; this is also called pH. The body is very sensitive to its pH level, so strong mechanisms exist to maintain it. When pH is imbalanced the protein become denatured and digested, enzymes lose their ability to function, and can cause death. Metabolic Acidosis and Alkalosis: Metabolic Acidosis and Alkalosis are caused by an imbalance of acids or bases and their excretion by the kidneys. Metabolic acidosis produces when the amount of acid in the body is increased through absorption of a substance that can be broken down to an acid.
At the bottom, it ranges from 4 celsius and 22 at the top. The pH changes because of topography and plants. The movement of water depends on the wind or draining
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.
Strong acids and strong bases are strong electrolytes and are assumed to ionize completely in the presence of water. Weak acids however, only ionize to a limited extend in water. Any weak or strong acids when in contact with any weak or strong alkali will start to undergo neutralization regardless of their volume. When an indicator which is present in the acid-base mixture and have experienced colour change, it indicates that the mixture is in right proportions to neutralize each other and is also known as the equivalence point.
In the late nineteenth century, acids were defined by Svante Arrhenius as substances that ionize in water to produce H+ (hydronium) ions, and bases as substances that ionize in water to produce OH- (hydroxide) ions (Chang, 2010). Arrhenius’s definition is known to be limiting thus, a broader definition was made by Johannes Bronsted. It is said that a Bronsted-Lowry acids are those that donate proton while a Bronsted –Lowry bases are those that accept proton (Bruice, 2005). When acids and bases react, a neutralization reaction occurs resulting to the formation of salts (Chang, 2010). pH is a reference of measure of how acidic or basic a particular substance is.
The topic of this research paper will cover over Ocean Acidification and the effects on marine ecosystems. Ocean acidification is the decrease in pH levels of the Earth 's oceans, due to overbearing carbon dioxide being brought by the atmosphere. The carbon dioxide is drawn by seawater, where the chemical reactions take place, which minimize the pH levels in the ocean, the carbonate levels and the important calcium carbonate which these sea creatures need. When carbon dioxide disperses in this ocean, it causes the levels of acidity to rise towards the the surface, where most shell growth in marine animals have been stopped and has created the cause of reproductive disorders in multiple fish. Part of the problem with ocean acidification is human activity.
