Homework Help: Chemistry

Posted by Richard on Wednesday, June 30, 2010 at 8:44am.

A buffer prepared by mixing equal amounts of the salts Na2HPo4 and NaH2PO4 to give a total phosphate concentration of 0.1M. What is the concentration of Na ions?

I believe it is 0.3M but am having trouble understanding why when I write out the dissociation of the Na2HPo4 and NaH2PO4. Thanks
