H2Cr3O4, also known as Chromic Acid, is an important chemical substance. Its English name is Chromic Acid. It consists of two hydrogen atoms, three chrom atoms, and four oxygen atoms, with atomic weights of 1, 52 and 16 respectively. The molecular weight of H2Cr3O4 is 154.07 g/mol. Its molecular structure includes a hydrogen ion and a chromate ion.
H2Cr3O4 is a strong acid, with an orange-red color and no characteristic smell. Its pH level is very low, indicating its strong acidic nature.
H2Cr3O4 can react with metals, non-metals, salts, and acids. For example, it can react with metals such as Fe, Cu to form chromate salts and hydrogen gas. It can also react with non-metals such as sulfur, phosphorus to form chrom salts and hydrogen gas. Furthermore, H2Cr3O4 can react with salts like NaCl, KCl to form chrom salts and hydrochloric acid.
H2Cr3O4 can be synthesized in the laboratory by reacting Chrom with H2SO4. On an industrial scale, it is produced by oxidizing Chrom in a strong acid environment.
