Effect of Acids and Bases on Water Equilibrium:
If an acid (H+) is added to the water, the equilibrium shifts to the left and the OH- ion concentration decreases.
Water Equilibrium: H2O ↔ H+ + OH-
If base (OH-) is added to water, the equilibrium shifts to left and the H+ concentration decreases.
Water Equilibrium Principle: The multiplication product (addition of exponents) of H+ and OH- ion concentration must always be equal to 10-14.
BOTH H+ and OH- ions are ALWAYS PRESENT in any solution. A solution is acidic if the H+ are in excess. A solution is basic, if the OH- ions are in excess.
Definition of pH, pOH, and pKw:
The concentrations of hydrogen ions and indirectly hydroxide ions are given by a pH number. pH is defined as the negative logarithm of the

When your blood has a pH below 7.35 it is considered too acidic and blood acidosis is associated with many health problems and diseases.
An acidic blood condition weakens the immune system, causes inflammation, headaches, aggravates diabetes and many other diseases. Some cells die in this acidic condition, but some cells actually try to adapt to survive by becoming abnormal malignant cells. Research has shown that in order to neutralize a glass of cola, you would have to drink 32 glasses of high pH alkaline water. Here’s a list of pH value in soft drinks, to show you how alarmingly acidic these beverages are. Human blood has a pH value ranging between 7.3 and 7.45. Anything under a pH of 5.5 can have a terribly adverse effect on the body. PRESERVATIVES
Preservatives are added into soft drinks to prevent spoilage, and to prolong shelf life. Storage conditions and time can affect the taste and flavor, and these preservatives help to preserve that.
The labels may list these as “permitted preservatives” but the exceeded amount can cause untold number of health
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.
Article of the Week Response “The Wrong Way to Think about California Water” is an argumentative piece of writing that was written by Michael Hiltzik in the Los Angeles Times. This article stresses mostly about the mere fact of how people waste water; especially in California. The major drought is causing people to use more water than we actually need to use normally. We don’t need to use as much water as we do
Report of Sylvia Frey’s Water From the Rock: Black Resistance in a Revolutionary Age Sylvia Frey’s Water from the Rock is meant to convey the deeper meaning of the American Revolution and the determination, line of events and the opportunity for black resistance in America. Frey lays the book out by discussing the economical and geographical differences in America and the effects of this on racial segregation. The pre-Revolution south in America had a highly successful economical basis in slavery.
As far as the circumstances concerning the pool being below the lower limit of 230.80 I have negative knowledge of that as it occurred on the shift presiding mine, which began at 12 noon on the 21st. When I assumed duty on the 21st of Oct at 1200 Hours the Headwater reading was 230.49 and we were at closed river having went to close river at approximately 0600 on the 21st. Although I had a double approaching upon arrival at noon and immediately thereafter 5 recreational Craft locking through as a group I immediately began to assess the situation. I first checked the water log system to ensure it showed all gates being at 0.00 or less which it did with a couple of gates reading like 0.03 which is common when at closed river. I then visually checked in front of
The effect of pH on the speed of enzyme interaction with substrate chemicals Hypothesis: About pH: If the pH level is less than 5, then the speed of the enzyme reaction will be slower. About temperature: If the temperature stays the same, then the speed of the enzyme reaction will not be completely affected. Background information: The function of enzymes is to speed up the biochemical reaction by lowering the activation energy, they do this by colliding with the substrate.
Do you think soft drinks should be separated for women and men? Or do you think everybody should be able to drink soft drinks? Well if you aren't for sure, i am here to tell you. The company that owns Dr.Pepper, made a new soft drink that appeals to men, and it is called Dr.Pepper 10. Dr.Pepper 10 was developed after the company's research found that men shy away from diet drinks that aren't perceived (or to become aware) as "manly" enough.
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.

Introduction: In this lab, of water in a hydrate, or a substance whose crystalline structure is bound to water molecules by weak bonds, is determined by heating up a small sample of it. By heating, the water of hydration, or bound water, is removed, leaving only what is called an anhydrous compound. Based on the percent water in the hydrate, it can be classified as one of three types: BaCl2O ⋅ 2H20, with a percent water of about 14.57%, CuSO4
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.
This conveys that sucrose concentration shall affect water potential, therefore the higher the sucrose concentration, the lower the water potential. This is how osmosis is linked to water potential and why experiments testing osmosis can be used to create methods to find and/or test water potential within plants. In addition to this, concentration of sucrose in a solution and in a plant cell or plant tissue shall have an effect on water potential.
PROCEDURE DETERMINATION OF PHOSPHORIC ACID IN THE SOFT DRINKS Black coloured soft drinks such as Coke from Coca Cola and Pepsi contains Phosphoric Acid in them. An experiment will be conducted here to determine the quantity of Phosphoric Acid content in the black coloured soft drinks. In the beginning of the experiment the preparation and standardization of a base solution will be made.
ABOUT THE SOFT DRINK INDUSTRY: The term "soft drink" refers to all types of nonalcoholic, carbonated, sweetened, flavored beverages. Nonalcoholic soft drink beverage market can be divided into fruit drinks and soft drinks. Soft drinks are available in glass bottles, aluminum cans; PET bottles are disposal containers can be divided into carbonated and non-carbonated drinks. Soft drinks are being manufactured since so long. There are various flavors in soft drinks that are lemon, orange, mango and cola.
