7. The pH = -log[+] for a solution. The pOH = -log[OH-] for a solution. The pH and pH are related and their sum is equal to 14 (pH + pOH = 14). If the concentration of a dilute solution of potassium hydroxide is 0.001 M, what is the pH of that solution? 8. Citric acid is produced by oranges. When citric acid dissolves in water, it produces a relatively small number of hydronium ions. Citric acid is best described...
