What Is the pH of Distilled Water?

The pH value can vary from 0 to 14 Solutions with a pH between 0 and 7 are acidic while those with a pH between 7 and 14 are basic Pure distilled water should be neutral with a pH of 7 but because it absorbs carbon dioxide from the atmosphere it's actually slightly acidic with a pH of 5 8

14 5: Reactions of Alcohols

The overall type of reaction is the same as that in the conversion of isopropyl alcohol to acetone Tertiary alcohols (R 3 COH) are resistant to oxidation because the carbon atom that carries the OH group does not have a hydrogen atom attached but is instead bonded to other carbon atoms The oxidation reactions we have described involve the formation of a carbon-to-oxygen double bond

Alcohol and Water

When boiling an ethanol-water azeotrope the boiling point of pure ethanol can never be reached since the 96/4 mixture boils first By adding benzene (warning: toxic!) pure ethanol can be produced since the benzene forms an azeotrope with the water which can then be extracted Nowadays molecular sieves provide a much healthier way to produce pure ethanol
