An analytical balance was used to weigh 200.01 mg of dry solid sodium acetate {nac2h3o2 ~ naac mw = 82.0343, pka (hc2h3o2 ~ hac) = 4.76} which was transferred to a 100.00 ml volumetric flask that was then filled to the line with carbonate-free water and mixed well. determine the ph of each of the solutions below.
a.) the original sodium acetate solution
b.) a 25.00 ml aliquot of the naac solution plus 25.00 ml of 0.100 m aqueous acetic acid (hac) solution
c.) a 25.00 ml aliquot of the naac solution plus 15.00 ml of 0.100 m aqueous hydrogen chloride solution
