Common corrosives are either strong acids, strong bases, or concentrated solutions of certain weak acids or weak bases. They can exist as any state of matter, including liquids, solids, gases, mists or vapors. Their action on living tissue (e.g. skin, flesh and cornea) is mainly based on acid-base reactions of amide hydrolysis, ester hydrolysis and protein denaturation. Proteins (chemically composed of ami… WebThe neutral substances that are the most well known are: water, table salt, sugar solution and cooking oil. Cooking oil is a neutral substance. We have learnt about three classes of substances: acids, bases and neutral substances. But, we cannot tell whether a substance is an acid, base, or a neutral substance, just by looking at it.
