Difference between organic acid and mineral acid Chemical substances with acidic characteristics are known as acids. A chemical species that may react with a base to generate a salt and water is known as an acid. Strong acids and weak acids are the 2 primary kinds of acids. Based on its chemical composition, acids can be classified as mineral acids or organic acids. Mineral Acids: What Are They? Mineral acids, often known as inorganic acids, are acids generated from inorganic compounds. Inorganic acids, then, are inorganic substances with acidic characteristics. Some inorganic acids contain oxygen atoms in their composition, and some don't. H2SO4 is an inorganic acid with oxygen atoms, for example. HCN, on the other hand, is an inorganic acid that lacks oxygen atoms. Some inorganic acids contain carbon atoms, whereas others have no carbon atoms in their chemical structure. HCN, for example, is an inorganic acid with a carbon atom. Organic Acids: What Are They? Acidic organic substances are known as organic acids. Organic acids must have a carbon atom in their composition because they are organic molecules. Carboxylic acid is by far the most common form of organic acid. A carboxylic acid's molecular formula can be written as RCOOH. –COOH is the functional group that causes the acidic characteristic. This group's hydrogen atom can be discharged as an H+ ion. This is due to the fact that the oxygen atom has more electrons and is therefore more electronegative than the hydrogen atom. As a result, the H atom can readily be isolated from the –COOH group.
