Using Ka to Calculate Percent Ionization
Calculate the percentage of HF molecules ionized in (a) 0.10 M HF solution, (b) a 0.010 M HF solution.
Using pH to Determine the Concentration of a Salt
Combined Effect of Cation and Anion in Solution - Summarized
An anion that is the conjugate base of a strong acid (e.g. Br-) will NOT affect the pH of the solution.
An anion that is the conjugate base of a weak acid (e.g. CN-) will increase the pH.
