Normality of \[\text{0}\text{.3 M }{{\text{H}}_{\text{3}}}\text{P}{{\text{O}}_{\text{4}}}\]solution is

A)  0.6 N                         

B)  0.1 N

C)  0.3 N                         

D)  0.9 N

Correct Answer: D

Solution :

\[\text{Normality = Molarity  }\!\!\times\!\!\text{  n}\] \[n=\]Number of replaceable H atom or OH groups in a molecule. In \[{{H}_{3}}P{{O}_{4}}\](orthophosphoric acid) the value of n=3. Hence, the correct option is [d].
