What is a Zinc hydroxide (Zn(OH)₂)?

Zinc hydroxide (Zn(OH)₂) is an inorganic compound composed of zinc and hydroxide ions. It typically appears as a white solid or precipitate at room temperature and is insoluble in water, displaying alkaline properties. Zinc hydroxide plays a significant role in various chemical reactions and industrial processes. One of its main uses is in neutralizing acidic wastewater. Zinc hydroxide reacts with acids to form zinc salts, making it useful in waste treatment. It is also employed as a catalyst in various chemical reactions, particularly in organic chemistry.

In the pharmaceutical and cosmetic industries, zinc hydroxide is used for its anti-inflammatory and antimicrobial properties, particularly in skin treatments. It is also used in sunscreens and skin creams. In agriculture, zinc is a crucial micronutrient for plant growth, and zinc hydroxide can be used as a source of zinc in fertilizers. Additionally, it has applications in water treatment, aiding in the purification of water by acting as a precipitate. Due to its alkaline nature, it must be handled with care, as it can react with acids to release harmful gases.
