Amphoteric hydroxides react with both alkalies and acids. Which of the following Group 2 metal hydroxides is soluble in sodium hydroxide?

A

`BeIOH)_(2)`

B

`Mg(OH)_(2)`

C

`Ca(OH)_(2)`

D

`Ba(OH)_(2)`

Text Solution

Verified by Experts

The correct Answer is:
A
`Be(OH)_(2)` dissolves in NaOH
`Be(OH)_(2) + 2 NaOH to Na_(2)BeO_(2) + 2 H_(2)O`
It is also soluble in HCL
`BeOH_(2) + 2HCl to BeCl_(2) + 2 H_(2)O`
Thus, `Be(OH)_(2)` is amphosteric in nature.
