If [⁻OH] > [H2O] , for an acid base reaction to produce salt, which direction will equilibrium favour?
Correct answer: A. Forward direction
- A. Forward direction
- B. All conditions are possible
- C. Reaction will be at equilibrium
- D. Reverse direction
Explanation
In a chemical reaction, a greater concentration of the reactant favors the forward reaction and a greater concentration of the product favors the backward reaction.Hydrogen and hydroxide ions of acids and bases respectively react together to make salt and water. If the concentration of the hydroxide ions is more than water, more water will be formed. So, the forward reaction will be favored.

About Chemical Equilibrium
Reversible reactions reach dynamic equilibrium when forward and reverse rates become equal, and Le Chatelier's principle predicts the effect of changing concentration, pressure or temperature. The chapter also covers solubility product, the common ion effect, buffer action and the conditions used in Haber's process, with equilibrium shifts distinguished from changes in the equilibrium constant.
