1) A 15.3 mL of a solution of Ba(OH)2 was titrated with
a 0.250 M HCl solution. It took 35.4 mL of
HCl solution to reach an endpoint. What was concentration of the Ba(OH)2?
The reaction is: Ba(OH)2 + 2HCl →
BaCl2 + 2H2O

2) 25.0 mL of a solution of Ca(OH)2 was titrated with
a 0.150 M HCl solution. It took 22.8 mL of
HCl solution to reach an endpoint. What was the molarity of Ca(OH)2
used?
The reaction is: Ca(OH)2 + 2HCl →
CaCl2 + 2H2O
