95% ethyl 乙醇 (pure) 是否餘下5% 有其他雜質?

the 5% is mainly water and traces of impurities (not much really) because by law 100% ethanol is not sold easily to people who are not from the hospital or the chemistry lab, due to alcoholics looking for stronger alcohols than beer and wine.

usually the 5% is a mixture of water impure sustance, and may be a small amount of benzene.

usually the 5% is water, but not benzene don't worry

雜不雜質是你決定
總之5%不是乙醇

不過呢
乙醇 是 ethanol
