1. A formic acid, sodium formate solution is made up by dissolving 0.010 more on
acid and 0.023 mole of sodium formate in 100 mL of water? What pH will the buna
solution be at? If 0.01 mole of NaOH is added to this solution what will be the resulting Ph?
(Kof formic acid = 1.8 · 104)

2. Calculate the H" ion concentration and the pH of formic acid solutions with the
following concentrations: 0.10 M, and 0.01 M. (Ka of formic acid = 1.8.10")

3. Find the pH of a solution made by diluting 35 mL of 4.5 M HNO3 to a final volume of
2.25 L.​
