Webb17 okt. 2014 · Acid-Base Reactions Of Alcohols. Alcohols are mild acids.Typical aliphatic (i.e. “alkyl”) alcohols such as ethanol, isopropanol, and t-butanol have a pK a of about 16-18, making them slightly more acidic than water. Alcohols that are in conjugation with a pi bond or aromatic ring will be more acidic since the conjugate base is resonance-stabilized. WebbAlcohols burn to produce CO2 and H2O. The amount of heat released is dependent on the bonds being broken and reformed and is the heat of combustion. In this experiment, you will measure the amount of energy produced when three different alcohols burn, and determine their molar heats of combustion
