A) solution of B-, a weak base , has a pH of 10.90.What is the molarity of B- if kb=3.24 x 10^-5?

2) 0.500 mol of A2 and 0.500 mol of B2 are placed in sealed container : the reaction is A2(g)+B2(g)---2AB at equilibrium , the flask contains 0.6400 mol of AB.What is the Kc at this temperature?

When a solution contains a weak acid and its conjugate base or a weak base and its conjugate acid, it will be a buffer solution. Buffers resist change in pH following the addition of acid or base. A buffer solution prepared from a weak acid (HA) and its conjugate base (A−) is represented as HA(aq)⇌H+(aq)+A−(aq) The buffer will follow Le Châtelier's principle. If acid is added, the reaction shifts to consume the added H+, forming more HA. When base is...
