Activity 4.1.2. Let's do this! Answer the following problems. Write your full solution on your answer sheet and box the final answer. 1. What is the pH of stomach acid, a solution of HCI with a hydronium ion concentration of 1.2 x 10-³ M? 2. Air-saturated water has a hydronium ion concentration caused by the dissolved CO2 of 2.0 x 10-M, about 20-times larger than that of pure water. Calculate the pH of the solution at 25 °C. 3. Calculate the hydronium ion concentration of a solution with a pH of -1.07. 4. What are the pOH and the pH of a 0.0125M solution of potassium hydroxide, KOH? 5. The hydronium ion concentration of vinegar is approximately 4 x 10-³M. What are the corresponding values of pOH and pH?
