Question

The normality of 0.3 m phosphoric acid as h3 po 3 is

Answer 1

Normality can be related with molarity as:

         Normality = Molarity × n- factor

where, n - factor can be acidity (or) basicity (or) point charge on salt (or) redox electron exchange.

Ortho Phosphorus acid has two acidic protons in exchange of acidic hydrogens.

So, n - factor is 2.

Now, solve the question dear.

Thanking you,
