Find the equivalent mass of `H_3PO_4` in the following reaction :
`Ca(OH)_(2) + H_(3)PO_(4) to CaHPO_(4) + 2H_(2)O`

A

49

B

98

C

32.66

D

147

Text Solution

Verified by Experts

The correct Answer is:
C
`Ca(OH)_(2) + H_(3)PO_(4) rarr CaHPO_(4) + 2H_(2)O`
In the above reaction n-factor of `H_(3)PO_(4)` is 2. `rArr` Equivalent weight `= (98)/(2) = 49`
