Expert Solution & Answer

Summary Introduction

To determine:

The classification of a solution is either acidic or basic.

Introduction:

In general, aqueous solutions may be divided into three categories based on the pH. They are the acidic, basic and neutral solutions. With a pH of 7.0, a solution is classified to be neutral whereas the pH is less than 7.0, the solution is considered to be acidic. When the pH of the solution is higher than 7.0 it is called as basic.

Explanation of Solution

Acidity and alkalinity of solution can be determined by the concentration of H+ in the solution. Acidic solutions have a high concentration of proton ions (H+). The basic solutions will have a low H+ concentration and a higher OH- concentration. An acid is any proton donor. A base is any proton acceptor.

Conclusion

Solution can be categorized as acidic, basic, or neutral based on the pH of the solution.

Awnser these Discussion Questions Answer these discussion questions and submit them as part of your lab report. Part A: The Effect of Temperature on Enzyme Activity Graph the volume of oxygen produced against the temperature of the solution. How is the oxygen production in 30 seconds related to the rate of the reaction? At what temperature is the rate of reaction the highest? Lowest? Explain. Why might the enzyme activity decrease at very high temperatures? Why might a high fever be dangerous to humans? What is the optimal temperature for enzymes in the human body?
