1) A solution of perchloric acid is prepared that has a molar concentration equal to the fourth and fifth digits of your Student ID Number divided by 105. What are pH and pOH in that solution at 25 °C?
2) A solution of nitric acid is prepared that has a molar concentration equal to the fourth and fifth digits of your Student ID Number divided by 104. What are the pH and pOH in that solution at 25 °C?
3) A solution of potassium hydroxide is prepared that has a molar concentration equal to the fourth and fifth digits of your Student ID Number divided by 103. What are the pH and pOH in that solution at 25 °C?
4) A solution of barium hydroxide is prepared that has a molar concentration equal to the fourth and fifth digits of your Student ID Number divided by 105. What are the pH and pOH in that solution at 25 °C? Assume complete solubility and complete ionization.
