Aqueous solution containing `1` mol of borax raects with `2` mol of acids. Thic is because of:

Options

A. formation of `2` mol of `B(OH)_(3)` only
B. formation of `2` mol of `[B(OH)_(4)]^(-)` only
C. formation of `1` mol each of `B(OH)_(3)` and `[B(OH)_(4)]^(-)`
D. formation of `2` mol each of `[B(OH)_(4)]^(-)` and `B(OH)_(3)`, of which only `[B(OH)_(4)]^(-)` reacts with acid

Answer

D

Explanation

`[B_(4)O_(5)(OH)_(4)]^(2-)+5H_(2)O hArr 2B(OH)_(3)("weak acid")+2[B(OH_(4))]^(-)` (salt)
