Consider the following equation Ca(OH)...

Consider the following equation
`Ca(OH)_(2)+H_(3)PO_(4) rarr CaHPO_(4)+2H_(2)O`
The equivalent mass of phosphoric acid `(H_(3)PO_(4))` is

A

`("Formula mass")/2`

B

`("Formula mass")/3`

C

`("Formula mass")/1`

D

`("Formula mass")/1.5`

Text Solution

Verified by Experts

The correct Answer is:
1
Since 1 formula unit of `H_(3)PO_(4)` releases only two `H^(+)` ions, the basicity of `H_(3)PO_(4)` in the given equation is two.
