Question

Consider the following aqueous chemical equilibrium of benzoic acid, a weak acid:

C₆H₅COOH _(aq) + H₂O_(l) = H₃O⁺_(aq) + C₆H₅COO^-_(aq)

1. Addition of H₃O⁺ to the chemical equilibrium( increases or decreases?) ______ the amount (moles) of the C₆H₅COO^- in the system

2. Addition of OH^- to the chemical equilibrium _________ the amount (moles) of C₆H₅COOH in the system

3. Removal of C₆H₅COO^- from the chemical equilibrium __________ the amount of H₃O⁺ in the system

4. Increasing the pH of the solution from the chemical equilibrium ___________ the amount of C₆H₅COOH in the system
