Acid-Base Homework Problem Set 1

This problem set was developed by S.E. Van Bramer for Chemistry 146 at Widener University.

  1. For the following reactions, write a balanced equation that describes what happens when the following are mixed. Identify the acid, base, conjugate base, and conjugate acid.
    1. Nitric acid and water
    2. Ammonia and water
    3. Nitric acid and ammonia
    4. Sulfuric acid and sodium hydroxide
    5. Sodium hydrogen sulfate and ammonia
    6. Acetic acid and water
    7. Acetic acid and sodium hydroxide

  2. Determine the equlibrium concentration of H3O1+ and OH1-. Identify the acid and the conjugate base (or the base and the conjugate acid). Calculate the pH.
    1. A 0.10 M solution of HNO3
    2. 1.00 g of HCl is diluted to 500.0 mL with water
    3. 10.0 g of HCl is diluted to 500.0 mL with water
    4. 5.00 grams of acetic acid is diluted to 250.0 mL with water
    5. 5.00 grams of sodium hydroxide is diluted to 500.0 mL with water
    6. 5.00 grams of ammonia is diluted to 500.0 mL with water
    7. 5.00 grams of sodium chloride is diluted to 500.0 mL with water
    8. 5.00 grams of potassium acetate is diluted to 500.0 mL with water
    9. 5.00 grams of sulfuric acid is diluted to 500 mL with water
    10. 5.00 grams of sodium hydrogen sulfate is diluted to 500.0 mL with water
    11. 5.00 grams of sodium sulfate is diluted to 500.0 mL with water
