Question

For the reaction Ca (OH)2 + H₂ PO3 → Ca HPO₃ + 2 H₂O The equivalent mass of H3 PO3 is (Molecular mass of H₂ PO3 is 82u)
a) 820
b) 410
c) 27.34
d 164
guys plz jaldi ans karo​

Answer 1

Answer:

hey here is your answer..

STEP BY STEP EXPLANATION:

EQUIVALENT MASS = molecular mass / basicity

Given molecular mass = 82

basicity of H3PO3 is 2

Equivalent mass = 82/2 = 41 unified mass
