Question

Is HCL a strong acid as concentration increases?

Answer 1

By definition, a strong acid is an acid for which the protonolysis......

Explanation:

By definition, a strong acid is an acid for which the protonolysis reaction with the solvent is almost complete, and the given equilibrium LIES STRONGLY to the RIGHT.......

`HX(aq) + H_2O(l) rightleftharpoonsH_3O^+ + X^-`

For `X=Cl, Br, I`, ionization is almost complete, and the solution is quantitative in `H_3O^+`. On the other hand, `HF`, is a weak acid, and the given equilibrium lies to the LEFT.....`K_a(HF)=6.76xx10^-4`.
