concentration of H+ in a solution is 10 - 3 M‚ what will the concentration of OH be in the same solution at 25° C? [OH-] = 10-11 M from (Kw= [H+][OH-]) Homework 1_Key BCH2333 Winter 2015 8. How many mL of a 0.4 M HCl solution are required to bring the pH of 10 mL of a 0.4 M NaOH solution to pH 7.0 (neutral pH)? Note: HCl and NaOH both completely dissociate in water (i.e.‚ no pKa calculation is necessary). 10 mL Have 4 mmol total of OH- therefore you need to add 4 mmol
