Answer

Brief Explanations:

According to the definition of an acid (a substance that increases the concentration of (H_3O^+) ions in solution by contributing a (H^+) ion), in the reaction (C_6H_5OH(aq)+H_2O(l)\to C_6H_5O^-(aq) + H_3O^+(aq)), (C_6H_5OH) donates a (H^+) ion (as it goes from (C_6H_5OH) to (C_6H_5O^-), losing an (H^+)) to (H_2O) (which accepts the (H^+) to form (H_3O^+)). (H_2O) here is acting as a base (accepting the (H^+)), (C_6H_5O^-) is a product (the conjugate base of (C_6H_5OH)), and (H_3O^+) is a product (formed by the acceptance of (H^+) by (H_2O)).

Answer:

(C_6H_5OH(aq))
