The value for Ka1, and Ka2, (dissociation constants) of oxalic acid are `5.1 xx 10^(-2)` and `5.2xx10^(-5)` respectively. Give the suitable reason for the large difference in these two values.

Explanation

To explain the large difference between the dissociation constants \( K_{a1} \) and \( K_{a2} \) of oxalic acid, we can break down the reasoning into several steps:

### Step 1: Understanding Oxalic Acid
Oxalic acid is a diprotic acid, which means it can donate two protons (H⁺ ions). Its chemical formula is \( C_2H_2O_4 \).

### Step 2: First Dissociation (Ka1)
The first dissociation of oxalic acid can be represented as:
\[
