Hydroxides are one of the best-known inorganic compounds, valued in many industries. An example of such a relationship is zinc hydroxide. What should we know about it? What is the process of obtaining zinc hydroxide? Here's a handful of the most important information. Published: 01-9-2023 Zinc hydroxide: summary formula, properties What is zinc hydroxide? The structural formula of this compound indicates that it is formed by a positive ion in the form of metal (zinc) and contains negative ions and hydroxyl groups. This composition also describes the hydroxide formula: Zn(OH) 2 . What are the characteristics of zinc hydroxide? The molecular weight of Zn(OH) 2 is 99.39 ± 0.02 g/mol. This: an odorless and hygroscopic solid with a loose consistency, slightly soluble in water (when we combine zinc hydroxide with water, the precipitates at the bottom of the container turn white and thicken). Zinc hydroxide powder is white or off-white in color (the color of zinc hydroxide may also resemble a whitish or light gray shade). There is one more typical feature of zinc hydroxide: the structure of this compound resembles diamond-shaped crystals.
Zinc hydroxide: obtaining How is zinc hydroxide formed? Chemists call the reaction to obtain Zn(OH) 2 a precipitation reaction, because thanks to the precipitation reaction the product obtained is in the form of a precipitate. What is needed to produce zinc hydroxide? How is this precipitate obtained? All that needs to be done is to combine a small amount of sodium hydroxide solution ( potassium hydroxide can also be used as a substitute) with a solution containing zinc salts. Is zinc hydroxide amphoteric? Amphoterism means that chemical compounds react as an acid or a base depending CZ Leads on the substances with which they combine. This property is exhibited by zinc hydroxide. The chemical nature of Zn(OH) 2 can be described as amphoteric because it behaves like an acid or a base in various configurations. How to check if zinc hydroxide is amphoteric ? When we combine it with a strong base, it will behave like an acid, and vice versa: when we combine it with strong acids, it will react like an alkaline compound. It is not surprising that amphoteric zinc hydroxide has found various applications in industry and everyday life. Zinc hydroxide – applications What is zinc hydroxide used for in everyday life? A solution of this compound or a powder form of Zn(OH) 2 can be used for the production of zinc salts, for example.
These salts have a cleansing, antibacterial and regenerating effect. Therefore, zinc hydroxide in the cosmetic industry indirectly functions as a raw material, thanks to which various types of body care products are made. These include, for example: face washing liquids, shower gels, intimate hygiene products, anti-dandruff shampoos and rinses, shampoos for daily hair care, soaps and foams for washing, preparations and cosmetics for normal and acne skin (creams, ointments, serums). The amphoteric and hygroscopic properties of zinc hydroxide are also highly appreciated in medicine and in the treatment of extensive injuries. It is a high-quality adsorbent, that is, a substance that perfectly absorbs and thickens other substances (for example, human blood). Bandages containing a hydroxide filler work well, for example, after surgical procedures that cause heavy bleeding. Surgical adsorbents protect the wound, which can then heal quickly and without complications.
