Interpretation:
The
Concept introduction:
A strong acid easily releases protons to a base or when dissolved in water. It readily participates in an acid-base reaction. A weak acid undergoes only slight ionization in solution. It does not release protons easily. The major species present in a solution of weak acid is the unionized molecular species. However, some ions are present as minor species. The extent of the ionization is determined by the ionization constant.
Answer to Problem 72E
The
Explanation of Solution
The equation for the dissociation of hypochlorous acid,
The dissociation constant,
The concentration of
The concentration of the reactant and products before and after ionization can be tabulated as shown below.
Where,
