Question

In the reaction
NaOH + H3PO4 - Na2HPO4 + H20, the
equivalent weight of H3PO4 (phosphoric
acid) is:
a. 98
b. 49
c. 32.66
d. 24.5
Ans:49
n-factor of H3PO4 for this particular reaction=2
(As only 2 hydrogen are getting replaced)
equivalent weight of H3PO4=molar weight/2
=98/2=49
​

Answer 1

Answer:

Ans:49

n-factor of H3PO4 for this particular reaction=2

(As only 2 hydrogen are getting replaced)

equivalent weight of H3PO4=molar weight/2

=98/2=49

Answer 2

49 is the answer isthe best
