Which of the following are Aprotic acids?

Question

1. H3PO2

1. H3PO4

1. H3PO3

1. H3BO3

Answer 1

We know that Aprotic acid(not Protic) is one that do not ionise in H2O to give a proton.

So from above example:

**1. H3PO2 - Monoprotic

1. H3PO4 - Triprotic

2. H3PO3 - Diprotic

3. H3BO3 - Aprotic(Not protic)**
