Phosphorus acid is a dibasic acid as: <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/2b7851b9de58720612449c49a8164b31-.png" /> only two replaceable hydrogens Therefore, normality = molarity × basicity = 0.3 × 2 = 0.60

Q. The normality of $0.3 M$ phosphorus acid $(H_{3} P O_{3})$ is

0.1

0.9

0.3

0.6

Phosphorus acid is a dibasic acid as :

only two replaceable hydrogens
Therefore, normality $=$ molarity $\times$ basicity $= 0.3 \times 2 = 0.60$
