Chemistry Help: Concentrations and pH?

Posted on 2014-04-17 08:22:00 in Chemistry by SETH

Yes, this is homework, but I am absolutely lost on this.



A. Calculate the concentrations of all ions and the pH of a solution containing 0.001 moles of H4SiO4 (a weak acid, treat it as monoprotic) per L of solution.



B. If 0.001 moles of the above acid was added to a liter solution that had a pH of 4.2, what % of the acid would dissociate?



H4SiO4 <-> H3SiO4- + H+ ,K1=10^-9.71



This is the last problem on this homework assignment and is worth the most points. Thanks in advance!
