1. 42.3 mL of 0.285 M HCl were used to titrate an NaOH solution
having a concentration of 0.714 M. What volume of base was
needed?
2. 81.7 mL of 1.34 M HNO3 were used to titrate 56.3 mL of an
LiOH solution. Find the concentration of the lithium hydroxide.
3. 63.9 mL of 0.560 M sulfuric acid solution was completely
neutralized by 28.3 mL of potassium hydroxide solution. What was
the concentration of the potassium hydroxide?
4. 0.472 M sulfuric acid was used to titrate a 0.388 M barium
hydroxide solution. The initial volume reading on the acid buret
was 34.42 mL and the final reading was 41.90 mL. If the initial
reading on the base buret was 63.25 mL, what was the final volume
reading on the base?
5. 71.1 mL of 0.695 M rubidium hydroxide neutralized 89.7 mL of
a sulfuric acid solution of unknown concentration. Find the
concentration of the acid.
6. A chemist needs to neutralize 25.5 L of 3.86 M chloric acid
(HClO3). What mass of sodium hydroxide is needed to
accomplish this?
