A metal $M$ readily forms water-soluble sulphate $M S O_{4}$ , water-insoluble hydroxide $M (O H)_{2}$ and oxide $M O$ . The oxide and hydroxide are soluble in $N a O H$ . The $M$ is:

Question

Q. A metal

M

readily forms water soluble sulphate

M S O_{4}

, water insoluble hydroxide

M (O H)_{2}

and oxide

M O

which becomes inert on heating. The hydroxide is soluble in

N a O H

. The

M

is

Answer 1

On moving down, the water solubility of alkaline earth metals decreases.O xide and hydroxides of alkaline earth metal are basic except Be which is amphoteric.

Therefore, metal is $B e$

A metal M readily forms water-soluble sulphate MSO4, water-insoluble hydroxide M(OH)2 and oxide MO. The oxide and hydroxide are soluble in NaOH. The M is:

The correct option is B Be On moving down, the water solubility of alkaline earth metals decreases.O xide and hydroxides of alkaline earth metal are basic except Be which is amphoteric. Therefore, metal is Be
