Problem: The acid-dissociation constant for hypochlorous acid (HClO) is 3.0x10 - 8.Calculate the concentration of HClO at equilibrium if the initial concentration of HClO is 7.1×10−3 M.

FREE Expert Solution

Equilibrium reaction:        HClO(aq) + H2O(l)  ClO-(aq) + H3O+(aq) 


Step 1: Construct an ICE chart for the reaction.


Step 2: Write the Ka expression

Ka=productsreactantsKa=[ClO-][H3O+]HClO

Solids and liquids are not included in the expression



Step 3: Calculate for x.
