the final step in the mechanism for the base promoted hydrolysis (saponification) of an ester is a deprotonation of a carboxylic acid by sodium hydroxide to give a carboxylate salt (RCO2Na). Draw a mechanism for this reaction, paying close attention to details such as lone pairs, formal charges and he use of curved arrows.
