Answer:
C6H5COOH + OH- —> C6H5COO- + H2O
Explanation:
C6H5COOH + OH- —> C6H5COO- + H2O
In the reaction above, C6H5COOH donate a proton(H+) to form the carboxylate ion C6H5COO-. The proton (H+) combines with the OH- to form H2O.
This can better be understood in the illustration below
C6H5COOH + NaOH —> C6H5COONa + H2O
