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

💡 Solution & Explanation

For weak acids at equal concentration, [H+] is ∝ Ka. The acid with lowest pKa (3.0) has highest Ka, hence highest [H+]. HNO2 has pKa = 3.0.
