Why is `K_(a_(2)) ltlt K_(a_(1))` for `H_(2) SO_(4)` in water ?

Text Solution

AI Generated Solution

To understand why \( K_{a2} \ll K_{a1} \) for \( H_2SO_4 \) in water, we can break down the dissociation of sulfuric acid into two steps and analyze the factors affecting the dissociation constants. ### Step-by-Step Solution: 1. **Dissociation of \( H_2SO_4 \)**: The first step of dissociation of sulfuric acid (\( H_2SO_4 \)) in water can be represented as: \[ H_2SO_4 \rightarrow HSO_4^- + H^+ ...
