Question

2.53) The equivalent mass of H,PO, and NaH,PO, in
the reaction are respectively:
2 NaOH + H,PO, Na,HPO, +2H,0
a) 49, 142
b) 49, 71
c) 98,71
d) 98, 142​

Answer 1

this question cld be confusing since the n factor of h3po4 is 3 yet the equivalent is not 98/3 becoz if a reaction is given then we r supposed to cal the equivalent on the basis of the H atoms lost or gained in that particular reaction..

hope it helps...
