Chromium hydroxide extra pure
Description
Chromium hydroxide extra pure refers to high-purity chromium(III) hydroxide, Cr(OH)₃, a gelatinous green inorganic compound used in analytical and laboratory applications. It appears as a green precipitate or powder with low solubility in water, acting as an amphoteric substance that dissolves in strong acids to form [Cr(H₂O)₆]³⁺ or in strong alkalis to form chromite ions, CrO₂⁻.
The compound has an undefined polymeric structure and is prepared by adding ammonium hydroxide to a chromium(III) salt solution. 'Extra pure' grades minimize impurities for precise uses like pigments, mordants, and catalysts in organic reactions.
It decomposes on heating to chromium(III) oxide and is irritant, requiring protective handling due to chromium toxicity.
