Professor Whoops attempts to make a 10^-7 M NaH2PO4 solution. The good professor accidently grabs the Na2HPO4 bottle. What pH did professor Whoops expect the solution to be? what was the actual pH of the solution as made? ( one approach : sketch a pC-pH diagram to solve this problem. For phosphoric acid, pKa,1=2.1, pKa,2=7.2, and pKa,3=11)
