In this experiment you will make a set of solutions containing different concentrations of CV+ by mixing different volumes of a stock CV+ solution with water to give final volumes of 3.0 mL. The stock solution of CV+ has a concentration of 2.0x10^-5M and is dark purple.
Use C1V1=C2V2 to calculate the volume of the stock 2.0x10^-5 M CV+ AND the volume of water to make a 3.0 mL sample of 4.0x10^-6 M CV+. Show calculations.

In this experiment you will be measuring pH for several
different solutions. A pH probe will be used rather than pH paper
as it will be more accurate.
You will be testing the pH of six solutions: deionized water,
0.1 M HCl, 0.1 M HCH3COO, 0.1 M NaCH3COO, 0.1
M NaOH, and a buffer made by mixing equal parts of
HCH3COO and NaCH3COO.
You will measure the pH of each solution three times:
