What is the hydronium ion concentration of a 0.150 M hypochlorous acid solution with K a = 3.5 × 10-8? The equation for the dissociation of hypochlorous acid is:

HOCl(aq) + H2O(l) ⇌ H3O+(aq) + OCl-(aq).

The concentration of is.

Explanation:

Let the initial concentration of weak acid be c m/liter and be change of concentration.

The reaction of an acid with water is given by the general expression

Initial Concentration              c                               0                0

Change in concentration     -                              +             +

Equilibrium Concentration     c-                                        

                [ For weak acid , the value of is so small, ∴]

The concentration of is    

Given equation is

The initial concentration of the hypochlorous acid solution is 0.150 M.

The ionization constant

The concentration of is  

                                                        = M

                                                      M
