Acids, Bases, Hydrolysis, Buffers, Titrations
1. Calculate the
pH
Ka = 3.5 x 10
and percent ionization for 0.50 M HOCN, cyanic acid
Transcribed Image Text:Acids, Bases, Hydrolysis, Buffers, Titrations 1. Calculate the pH Ka = 3.5 x 10 and percent ionization for 0.50 M HOCN, cyanic acid
2. Calculate the pH of a solution that is 0.25 M HNO3 and 0.100 M HC2H3O2.
Ka = 1.8 x 10° for HC2H3O2
3. a. Calculate pH of a solution that is 0.300 M HC2H;O2 and 0.400 M HOCI
Ka = 1.8 x 10 for HC2H3O2
Ka = 2.9 x 10° for HOCI
b. Calculate the percent ionization of the HOCI in the above solution.
4. Calculate the concentrations of H2S, HS, S, and the pH of a 0.25 M solution
of H2S. Ka1 = 1.1 x 107
12
Ka2 = 1.0 x 10
