Liquid Actual BP Literature BP Percent Error Calculation % Error Ethyl acetate 73º 77º ((73-77)/77) x 100 5.19% The classic example of adding salt to water leads to a phenomenon named “Boiling Point Elevation.” Impurities form chemical bonds with the solvent in which they are‚ holding it together in liquid form. Breaking those bonds is difficult‚ causing a rise in boiling point. A 5.19% error could have occurred from the temperature probe being situated too high above
