Question

Calculate the degree of ionization of 0.05M acetic acid if its pKa value is 4.74. How is the degree of dissociation affected when its solution also contains (a) 0.01M (b) 0.1M in HCl ?

The ionization constant of dimethylamine is 5.4 × 10–4. Calculate its degree of ionization in its 0.02M solution. What percentage of dimethylamine is ionized if the solution is also 0.1M in NaOH?

The addition of NaCl to a saturated solution of AgCl will:

Calculate the solubility of calcium fluoride (CaF2) in a solution that already contains 0.1 M NaF. (Ksp of CaF2 = 3.9 x 10-11)
