What is the concentration of OH– in a 0.083 M NaOH solution?

Find the pH of a 0.183 M aqueous solution of hypobromous acid (HOBr), for which Ka = 2.06 × 10–9.

Calculate the pH at the equivalence point for the titration of 50.0 mL of 0.20 M NH3 with 0.20 M HCl. [Kb(NH3) = 1.8 × 10–5]

A 35.0-mL sample of 0.20 M LiOH is titrated with 0.25 M HCl. What is the pH of the solution after 23.0 mL of HCl have been added to the base?

Calculate the pH of a 0.021 M NaCN solution. [Ka(HCN) = 4.9 × 10–10]

If the pH of a buffer solution is greater than the pKa value of the buffer acid, the buffer will have more capacity to neutralize added base than added acid.
