When 0.05 moles of the following acids are dissolved in 1000 ml of , the will be greatest in — Ionic Equilibrium Chemistry Question

💡 Solution & Explanation

The greatest $[\text{H}^+]$ corresponds to the strongest acid, which is the one with the highest $K_a$, or equivalently, the lowest $pK_a$. Among the given options, $\text{HNO}_2$ has the lowest $pK_a$ (3.0), meaning it will dissociate the most and produce the greatest $[\text{H}^+]$.
