Calculate the pH of centimolar solution of monoacidic weak base. Which is 10 % dissociated in its aqueous solution?

Step-by-step solution

pH of a Weak Base Solution A centimolar solution of a monoacidic weak base with a 10% dissociation has an initial concentration C = 10⁻² M and degree of dissociation = 0.1 . The hydroxide ion concentration is given by [ OH ⁻] = C = 10⁻² 0.1 = 10⁻³ M. The pOH is calculated as - (10⁻³) = 3 , and since pH + pOH = 14 , the pH is 14 - 3 = 11 . Final answer: 11
