Solution

1. $H {NO}_{3} + NaOH \to$ $Na {NO}_{3} + H_{2} O$
Strong acids react with strong bases to produce neutral salt and water.

2. ${CH}_{3} COOH + KOH \to$ ${CH}_{3} COOK + H_{2} O$
Weak acids react with strong bases to produce basic salt and water.

3. $HCl + {NH}_{4} OH \to$ ${NH}_{4} Cl + H_{2} O$
Strong acids react with weak bases to produce acidic salt and water.
