EXERCISES, LESSON 9
INSTRUCTIONS: Answer the following exercises by writing the answer in the space
provided at the end of the question.
After you have completed all the exercises, turn to "Solutions to Exercises" at the end of
the lesson and check your answers. For each exercise answered incorrectly, reread the
material referenced with the solution.
What is the pH of a 4.00 X 10-4 mol/L HCl solution?
What is the pH of a 0.100 mol/L HC2H3O2 that ionizes 1.3
What is the pOH of a 0.250 mol/L H2SO4 solution? (NOTE: Use the given
concentration for pH and pOH calculations that involve polyprotic acids, that is,
What is the pH of a 1.40 X 10-2 mol/L Ca(OH)2 solution? (NOTE: To
determine the actual hydroxide concentration of this and like compounds,
multiply the given concentration by the number of hydroxide ions per molecule.)
