b.Is the solution acidic, basic or neutral

2.Enough of a monoprotic acid is dissolved in water to produce a 0.0194 M solution. The pH of the resulting solution is 6.26. Calculate the Ka for the acid.

3.The Ka of a monoprotic weak acid is 6.58 × 10-3. What is the percent ionization of a 0.118 M solution of this acid?

4.Consider three generic acids with the following relative stengths: HX > HY > HZ Rank the strengths of their conjugate bases.

5.For the diprotic weak acid H2A, Ka1 = 2.4 × 10-5 and Ka2 = 6.0 × 10-7. What is the pH of a 0.0750 M solution of H2A? What are the equilibrium concentrations of H2A and A2- in this solution?

6.A solution of household bleach contains 5.25% sodium hypochlorite, NaOCl, by mass. Assuming that the density of bleach is the same as water, calculate the volume of household bleach that should be diluted with water to make 500.0 mL of a pH = 10.26 solution.
