Chapter 7 Lab Report

Background Research pH is a measure of the potential hydrogen ion concentration of a solution. Solutions that have low pH’s or a ph level below 7 are considered acidic. Solutions that have a high pH level or above 7 are considered basic. The pH scale measures how acidic or basic a solution may be. Some examples of solutions that have high acidity and a low pH level are Battery acid, lemon juice, and vinegar. Some solutions that are basic and a high pH level are soapy water, baking soda, and drain cleaner. Temperature plays a role on how high or low a solutions pH level is. For example, the colder the solution the less acidic it would be therefore it would have a high pH level. For warmer solutions there would be a lower pH level and high acidity. Some interesting facts are when swimming if a pool has a high or low pH level you could get dry skin and burning eyes. Another interesting fact is that ph is important in many things such as medicine, biology, chemistry, food, science and many more. Orange juice pH ranges from 3.3 to 4.19, but generally around 3.5. Citric acid is what gives the orange its acidity, and also its sour flavor. This means that it has a high to moderately high acidity.
Scientific Concepts:
Acids - Compounds that have properties with the kinds of reactions they undergo. Acids also release or donate hydrogen ions. This relates to our lab because orange juice is filled with citric acid, and we are testing the amount of acid (pH)
