A: Quick Answer Some possible sources of errors in the lab includes instrumental or observational errors. How many grams of solid sodium hydroxide would be required to saponify 16 mL olive oil, assuming it was PURE glyceryl trioleate? A: An esterification lab creates esters from the reaction between alcohols and carboxylic acids. Therefore a large sampling does not of itself ensure greater accuracy. http://maxspywareremover.com/of-error/what-are-sources-of-error-in-chemistry.php
