1. The problem statement, all variables and given/known data A solution was prepared by dissolving 0.02 moles of acetic acid (HOAc; pKa = 4.8) in water to give 1 liter of solution. a) What is the pH? b) 0.008 moles of concentrated sodium hydroxide (NaOH) was then added to this solution. What is the new pH? (In this problem, you may ignore changes in volume due to the addition of NaOH). c) An additional 0.012 moles of NaOH is then added. What is the pH? 2. Relevant equations pH = -log [H+ (aq)] pH = pKa + log [A- (aq)]/[HA (aq)] 3. The attempt at a solution a) pH = pKa + log [A- (aq)]/[HA (aq)] = 4.8 + log (0.02 mol/1 L) = 4.8 + log (0.02) = 4.8 - 0.301 = 4.699 Can I get this problem checked? I also am not sure on how to approach parts b and c. Thanks.
