The comparison of acidic strengths of two monobasic acids may be done by comparing the hydronium ion concentrations of their aqueous solution of the same molar concentration. The dissociation constants of the acids HA and HB are 4×10−6 and 2.5×10−9 respectively. How many times is HA stronger than HB? Assume that for both the acids, the degree of dissociation at the concentration taken is negligible.

Answer» The comparison of acidic strengths of two monobasic acids may be done by comparing the hydronium ion concentrations of their aqueous solution of the same molar concentration. The dissociation constants of the acids $H A$ and $H B$ are $4 \times 10^{- 6}$ and $2.5 \times 10^{- 9}$ respectively. How many times is $H A$ stronger than $H B$ ? Assume that for both the acids, the degree of dissociation at the concentration taken is negligible.
