Aqueous solution containing 1 mol of bor...

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

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

Text Solution

Verified by Experts

The correct Answer is:
D
`[B_(4)O_(5)(OH)_(4)]^(2-)+5H_(2)O hArr2B(OH)_(3) "weak acid"+2[B(OH_(4))]^(-)("salt")`
