Final answer:
Triacylglycerol will be completely hydrolyzed when three equivalents of NaOH are used in saponification, forming glycerol and three soap molecules.
Step-by-step explanation:
If three equivalents of NaOH are used for triacylglycerol saponification, the triacylglycerol will be completely hydrolyzed. This is because a triacylglycerol molecule consists of a glycerol backbone esterified with three fatty acid molecules. For complete hydrolysis and saponification, each ester bond requires one equivalent of a strong base such as NaOH to break down into glycerol and the sodium salts of the fatty acids, which are soap molecules. As the esterification reaction is reversible, providing three equivalents of NaOH ensures that each of the three ester bonds in the triacylglycerol is hydrolyzed, leading to the formation of one molecule of glycerol and three soap molecules, each being a sodium salt of the corresponding fatty acid.
