1. Calculate the pH when 24.9 mL of 0.011 M HCl is added to100.0 mL of the above buffer.
2. Calculate how many mL of 0.100 M NaOH are needed toneutralize completely 91.0 mL of 0.0600 MH2SO4 (forming Na2SO4and water).
3.
Calculate the pH of 0.057 M phosphoric acid(H3PO4, a triprotic acid). Ka1 =7.5 x 10-3, Ka2 = 6.2 x 10-8, andKa3 = 4.8 x 10-13.
Hint, if you are doing much work, you are making the problem harderthan it needs to be.
