What happens to the position of equilibrium when a base is added to an acid or vice versa?
gpt
Adding a base to an acid decreases the concentration of the acid, causing the equilibrium to shift to the left-hand side. When a base is added to an acid, such as hydrochloric acid and sodium hydroxide, they neutralize each other, leading to a shift in the equilibrium.
Explanation: In a chemical equilibrium between an acid and a base, the addition of one reactant affects the concentration of the other, causing the equilibrium to shift. The acid and base neutralize each other, leading to a decrease in the concentration of one or both reactants, resulting in a shift in the equilibrium position.
