WebApr 22, 2024 · There are three grades of ethanol commonly used in the lab. 1) 95% (95.6%) Ethanol This is the highest concentration of ethanol you can get by distillation because 95.6% ethanol is an azeotrope, which means the vapor state has the same ethanol-to-water ratio as the liquid state. 2) Absolute (99–100%) Ethanol Ethanol is a neutral molecule and the pH of a solution of ethanol in water is nearly 7.00.
