the acid dissociation constant of dichloroethanoic acid is 0.033 . calculate the concentrations of hydrogen ions
Wouldn't it depend on the concentration, or the amount present?
What's the concentration of the acid?
To calculate the concentration of hydrogen ions in a solution, we need to know the acid dissociation constant (Ka) and the initial concentration of the acid. In this case, we are given the acid dissociation constant (Ka) of dichloroethanoic acid, which is 0.033.
The acid dissociation constant, Ka, is defined as the ratio of the concentration of the dissociated form of the acid (H+) to the concentration of the undissociated form. Mathematically, it is represented as:
Ka = [H+][A-] / [HA]
where [H+] represents the concentration of hydrogen ions, [A-] represents the concentration of the conjugate base, and [HA] represents the concentration of the undissociated acid.
Since we want to calculate the concentration of hydrogen ions ([H+]), we rearrange the equation as follows:
[H+] = (Ka * [HA]) / [A-]
where [A-] represents the concentration of the conjugate base, and [HA] represents the initial concentration of the acid.
However, we are not given the initial concentration of dichloroethanoic acid ([HA]). Without this information, we cannot calculate the concentration of hydrogen ions ([H+]).
