Question

While doing a science practical experiment,a student left a bottle opened after usage which contained solid sodium hydroxide. When the student visited the laboratory again after few days and found only liquid sodium hydroxide in the bottle this is due to the _____ property of sodium hydroxide
1) hygroscopic 2)deliquescence 3)dehydration 4)dissociation

Answer 1

Answer:

2) deliquescence

Explanation:

if you keep sodium hydroxide in bottle. This Chemical react with water.

Answer 2

Hygroscopic

Explanation:

• In the given statement, the property of sodium hydroxide is the hygroscopic nature of sodium hydroxide.
• The reason for its hygroscopic nature is that Na cations and hydroxide anions have the readiness to form charge-assisted hydrogen bonds with the moisture.
• These bonds are stronger than those bonds formed between the molecules of water that are neutral.
• Hence, the correct option is (1) hygroscopic.
