Exercise 7. Compared to a solution at pH5, a solution of the same volume at pH 9 has
times more/less (circle the correct) hydrogen ions.
Exercise 8. Sean got a BioBS and because he always was interested in plants, he accepted a job as Plant
Research Associate at a Northeast University. He is developing a fertilizer to help soil maintain an optimal
pH for plant growth. The fertilizer he is using has a [H+] concentration of 0.00023 moles/liter. What is its
pH?
