Explanation Hydrochloric acid is a strong acid and it completely dissociates in water. This can be represented as follows; HCl ( a q ) + H 2 O ( l ) → H 3 O + ( a q ) + Cl − ( a q ) The concentration of hydrochloric acid is assumed as 1.0 mol ⋅ L − 1 . Therefore, 1.0 mol ⋅ L − 1 of HCl dissociates to give 1.0 mol ⋅ L − 1 of H 3 O + and 1.0 mol ⋅ L − 1 of Cl − . The pH of the solution can be calculated using the formula of pH as follows: pH = − log [ H 3 O + ] = − log ( 1.0 mol ⋅ L − 1 ) = 0.0 Hence, the pH of hydrochloric acid solution is 0.0 . The hydrochloric acid solution is diluted to 12 % from initial concentration. This means the concentration of hydrochloric acid is reduced to 12 % from 1.0 mol ⋅ L − 1 . Therefore, the concentration of HCl is calculated as follows: [HCl] = 1
