Calculate the concentrations of all the species present in 0.1 M `H_3PO_4` solution.
Given : `K_1=7.5xx10^(-3), K_2=6.2xx10^(-8)` and `K_3=3.6xx10^(-13)` .

Explanation

To calculate the concentrations of all species present in a 0.1 M solution of \( H_3PO_4 \), we will follow the steps of dissociation of the acid and use the provided dissociation constants \( K_1, K_2, \) and \( K_3 \).

### Step 1: Dissociation of \( H_3PO_4 \)

The first dissociation of phosphoric acid can be represented as:

\[
H_3PO_4 \rightleftharpoons H^+ + H_2PO_4^-
