Answer
(a) To the left.
(b) To the right.
Work Step by Step
(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.
