Homework Help: Chemistry

Posted by Anne on Thursday, October 25, 2012 at 11:43pm.

In an experiment to measure the solubility of Ba(OH)2 x 8H2O in water, an excess of solid Ba(OH)2 x 8H2O was stirred with water overnight. the saturated solution was allowed to stand until all the undissolved solid had settled. a 10.00mL sample of the clear supernatant liquid was titrated with 0.1250 M HCl. If 31.24 mL of 0.1250 M HCl was required to neutralize the hydroxide ion in the saturated solutions, what was the molarity of Ba(OH)2 x 8H2O in the saturated solution?
