Many useful chemical reactions or processes involve hydroxide or hydroxide ions. Sodium hydroxide is used in industry as a strong base, potassium hydroxide is used in agriculture, and iron hydroxide minerals such as goethite and limonite have been used as iron ore. The aluminium ore bauxite is made mainly out of aluminium hydroxides.
Most inorganic hydroxide salts do not dissolve in water.
Uses of hydroxidesEdit
Many useful chemicals and chemical processes involve hydroxides or hydroxide ions. Sodium hydroxide is used in factories as an alkali, potassium hydroxide is used in farming, and iron hydroxide have been used as low grade brown iron ore.
