When borax is dissolved in water:...

When borax is dissolved in water:

A

`B(OH)_(3)` is formed only

B

`[BH_(2)(NH_(3))_(2)]^(+) [BH_(4)]^(-)` is formed only

C

both `B(OH)_(3)` and `[B(OH)_(4)]^(-)` are formed

D

`[B_(3)O_(3)(OH)_(4)]^(-)` is formed only

Text Solution

Verified by Experts

The correct Answer is:
C
`[B_(4)O_(5)(OH)_(4)]^(2-)+5H_(2)OhArr2B(OH)_(3)+2[B(OH)_(4)]^(-)`
or
`[B_(4)O_(7)]^(2-)+7H_(2)Oto2B(OH)_(3)+2[B(OH)_(4)]^(-)`
