A buffer solution is composed of 1.723 g ofKH2PO4and 5.351 g of Na2HPO4 . ( ka for dihydrogen phosphate ion is 6.2x10^-8 .)
pH =
Mass = g
A-What is the pH of the buffer solution?
B-What mass of KH2Po4 must be added to decrease the buffer solution pH by 0.10 unit from the value calculated in part a?
