Zinc hydroxide (ZnOH) is a hydroxide compound. It is soluble in dilute acid solutions, hygroscopic, and amphoteric. A white flocculent precipitate forms, and it is insoluble in alcohol. It is an effective Lewis acid.
Zinc is a trace metal that is essential for humans. It is used in many applications, including dyes and pesticides. It is also used in surgical dressings to absorb blood after a surgery.
Zinc hydroxide is formed by combining sodium hydroxide solution with zinc salts. It is an intermediate in pigment production, and it is used in the manufacture of zinc alloy. The crystalline form of zinc hydroxide has a diameter of about two micrometres.
Zinc is a metal that is found in many enzymes. These enzymes break down proteins. Carboxypeptidase, an enzyme that digests proteins, is a good example of a zinc-containing enzyme. There are more than a thousand transcription factors that are dependent on the metallothioneins, which are necessary for the function of most proteins.
Zinc hydroxide is a very good adsorbent. This is because it binds to other substances, such as amino acids, to make them thicker. As a result, it thickens wounds and promotes healing.
In addition to its role as an adsorbent, it is also useful as a fixative in dressings. It is also an effective mordant. Among other uses, it is an important component of a zinc-containing compound, and is often applied to galvanized metals.
Zinc is a brittle metal at room temperature. When it is deoxidized, it becomes silvery gray.
