## Chemistry (7th Edition)

(a) 1. Identify the acids and bases: Acids: $HF$ and $HNO_3$ Bases: $F^-$ and $N{O_3}^-$ 2. Analyze the table 15.1, and determine which one is stronger for each type: Acid: $HNO_3$ Base: $F^-$ - Since these 2 eletrolytes are on the right side of the reaction, it will proceed from right to left. (b) 1. Identify the acids and bases: Acids: $N{H_4}^+$ and $HC{O_3}^-$ Bases:$NH_3$ and $C{O_3}^{2-}$ 2. Determine which one is stronger for each type (Use table 15.1): Acid: $N{H_4}^+$ Base: $C{O_3}^{2-}$ - Since these 2 electrolytes are on left side, the reaction will proceed from the left to the right.
