The pH of a hypoiodous acid/sodium hypoiodite buffer in which the concentration of the weak acid component is 0.280 M and the concentration of the conjugate base is 0.110 M is 10.23. Suppose 0.733 g of solid NaOH are added to 100 mL of this buffer solution. What is the pH after the addition? Clickhere for the table of Ionization Constants of Weak Acids.
