Homework Help: CHEMISTRY TITRATION Q

Posted by LISA on Wednesday, December 15, 2010 at 2:30pm.

The titration of 25.00mL of Ba(OH)2 solution with an aqueous solution of 0.500 M HCl reaches an end point when 30.20 mL of the HCl solution is added. Determine the concentration of M of the Ba(OH)2 solution.


Soo 25.00mL=0.025L
30.20mL= 0.0302L

moles= MxL (0.500M)(0.0302L)=0.5302 moles of HCl and since the moles are the same at the end point than 0.5302 is moles of Ba(OH)2 too?

M=moles Ba(OH)2/initial L 0.5302/0.025L= 21.2M is my answer

but the book says the answer is 0.302M
what have I done wrong?? Thanks!!
