What is the pH of 100 mL of a solution made using 5 mL of 1 M Na2 HPO4 and 5 mL of 1 M NaH2PO4? What is the pH of 100 mL of a solution made using 5mL of 1M Na₂HPO4 and 5mL of 1M NaH₂PO4?

C To add an H atom in basic solution, add an H20 to the side that needs the H atom, and also add an OH" to the other side. (HOH has one more H than OH"). How many H20 molecules should be added to the right side? How many OH ions should be added to the left? OH" + HS S+ H20 Number of OH ions = Number of H20 molecules =
