An aqueous solution contains 0.050 M of methylamine. The concentration of H⁺ in this solution is ________ M. K_b for methylamine is 4.4 × 10^-4.

Question

Quizplus · Accepted Answer

Methylamine is a weak base, and its Kb is given. To find the concentration of H+, we first calculate the concentration of OH- using the formula for Kb, then use the water dissociation constant (Kw = 1.0 × 10^-14) to find H+. The concentration of OH- is approximately 4.7 × 10^-3 M, leading to an H+ concentration of approximately 2.2 × 10^-12 M.
