Calculate the pH of a solution with a hydrogen ion concentration of 0.001 M.
How might a decrease in pH affect enzyme activity in a biological system?
Given that lemon juice has a pH of 2, what can be inferred about its hydrogen ion concentration compared to pure water?
A solution's pH changes from 7 to 5. How might this affect the activity of an enzyme that has an optimal pH of 7?
If bleach has a pH of 12, what can be inferred about its hydroxide ion concentration compared to pure water?
Explain how the concept of reciprocals is used in the calculation of pH.
