Academics

1. Define the following terms by means of an equation, or a definition.

a) Brønsted-Lowry acid

b) Brønsted-Lowry base

2. In the opening statement of this lab it is said that "Carbon dioxide, CO2, is the most important acid-producing compound in our atmosphere; rainwater is therefore naturally slightly acidic because of the dissolved carbon dioxide".

a) Show by means of an equation why carbon dioxide produces an acidic solution.

b) SO2 and NO2 are also acidic anhydrides. Write equations showing this behavior.

3. Predict the pH of the following 0.10 M solutions (neutral, acidic, or basic)
NaCl, KCN, NH4Br, NaHSO3

4. Identify the acid and base used in the preparation of the following salts.
KCN, SrBr2

5. You are asked to prepare a solution of a particular salt that has a pH 8.3 (your choices are KCN, NH4Cl, KNO2, or BaCl2.). What molarity of which salt should you choose? (Hint: look up the ionization constant)
