A monoprotic weak acid, HA, dissociates in water according to the reaction
A monoprotic weak acid, HA, dissociates in water according to the reactionHA(aq)+H₂O(l)⇌H₃O⁺(aq)+A-(aq)The equilibrium concentrations of the reactants and products are [HA] =0.270 M,[H₃O⁺]=3.00 × 10-4 M, and [A-]=3.00 × 10-4 M. Calculate the Ka value for the acid HA.

During exercise when the body lacks an adequate supply of oxygen to support energy production, the pyruvate that is produced from the breakdown of glucose is converted into lactate. High lactate levels can lead to acidity in the muscle cells as some of the lactate hydrolyzes to lactic acid. The dissociation of lactic acid to lactate is shown in the reaction. Lactic acid has a p?a of 3.86. Lactic acid dissociates into the lactate ion and a hydrogen ion. The...
