Which of the following statements is TRUE about HOCH2COOH and H2NCH2COOH?

A	Both are insoluble in water.
B	Both can form zwitterion.
C	Both can be obtained from hydrolysis of protein.
D	Both can easily dissolve in sodium hydroxide solution.

Explanation:

Detailed explanation-1: -Solution : As ‘Zn(OH) (2), BeO, Al (2)O (3) ‘ are amphoteric, so they can react with both HCl and NaOH.

Detailed explanation-2: -So, hydrochloric acid reacts with sodium hydroxide solution to form sodium chloride and water. This reaction can be represented as: Hydrochloric acid + Sodium hydroxide → Sodium chloride + Water. Q.

Detailed explanation-3: -"When sodium peroxide dissolves in water, it is hydrolyzed and forms sodium hydroxide and hydrogen peroxide."

Detailed explanation-4: -When sodium hydroxide and hydrochloric acid react, they neutralise each other and form common salt (salt) and water. So, the given statement is true.
