Interpretation: The acid dissociation constant of saccharin is to be calculated.
Concept introduction: The ratio of the concentration of the ionized form of an acid to the concentration of the unionized form of the acid is known as the dissociation constant or ionization constant. It is denoted as
The dissociation constant
Answer to Problem 102A
The dissociation constant
Explanation of Solution
Given:
The concentration of saccharin is
pH of the aqueous solution of saccharin is
The chemical equation for the dissociation of the saccharin is written as follows:
The concentration of hydrogen ions is calculated by the use of pH value.
The ICE table is constructed below:
