Which property is shown by the alkali sodium hydroxide?

1. It has a pH less than pH 7
2. It produces a gas when it is warmed with ammonium chloride
3. It turns blue litmus red
4. It turns Universal Indicator green

Correct answer: It produces a gas when it is warmed with ammonium chloride

Solution

Sodium hydroxide is a strong alkali, and when warmed with ammonium chloride it displaces ammonia gas from the ammonium salt. The other options describe acidic behavior or a neutral/weakly alkaline pH range, not this reaction.
