Chromium Hydroxide – 500 gram Packs

Chromium Hydroxide is an inorganic chromium compound used in selected laboratory investigations involving metal hydroxides, precipitation reactions, and inorganic synthesis. Commonly identified as Chromium(III) Hydroxide or Chromic Hydroxide, it has the idealized chemical formula Cr(OH)₃ and contains chromium in the +3 oxidation state. The material is generally insoluble in water and can react with suitable acids and strong bases, demonstrating amphoteric behaviour. These properties make it relevant to experiments involving chromium(III) chemistry, hydroxide formation, and the preparation of selected chromium-containing compounds. In college laboratories, university departments, and research centres, Chromium Hydroxide may be used when its composition and physical properties meet the requirements of the intended procedure. Commercial material can contain associated water, so its exact composition should be considered when performing quantitative calculations. Appropriate protective equipment and established chemical handling procedures are essential.

Frequently Asked Questions About Chromium Hydroxide

What is Chromium Hydroxide used for in laboratories?

Chromium Hydroxide is used in selected inorganic chemistry investigations involving precipitation, metal hydroxides, and chromium(III) reactions. It may also serve as a starting material for preparing selected chromium-containing compounds and materials. Its suitability depends on the material’s composition and the requirements of the experimental method.

What is the chemical formula of Chromium Hydroxide?

The idealized molecular formula of Chromium(III) Hydroxide is Cr(OH)₃, and its empirical formula is CrH₃O₃. The theoretical formula mass is approximately 103.02 g/mol. Commercial hydrated material may contain additional associated water, so its actual composition and effective formula mass can differ.

What is the CAS number of Chromium Hydroxide?

CAS 1308-14-1 is associated with Chromium(III) Hydroxide and hydrated forms of the material. Because commercial chromium hydroxide may contain variable amounts of water, the exact composition should be checked when using the identifier for laboratory inventory, purchasing, or quantitative calculations.

Why is Chromium Hydroxide described as amphoteric?

Chromium(III) Hydroxide is described as amphoteric because it can react with acids and strong bases under suitable conditions. This behaviour makes it useful for selected investigations of metal hydroxides and inorganic reaction chemistry. Experimental procedures should account for the hazards and compatibility of all reagents involved.

How should Chromium Hydroxide be stored and handled safely?

Store Chromium Hydroxide in a tightly closed, compatible container in a suitable dry storage area. Avoid generating or inhaling dust and use appropriate gloves, protective clothing, and eye protection. Consult the current Safety Data Sheet for specific ventilation, incompatibility, spill response, and disposal requirements.

Storage Conditions for Chromium Hydroxide

Store Chromium Hydroxide in a tightly closed, chemically compatible container in a cool, dry, well-ventilated area. Protect it from contamination and unnecessary exposure to moisture. Keep it segregated from incompatible substances according to the applicable Safety Data Sheet. Maintain clear container identification and restrict access to authorized laboratory personnel.

Precautions for Handling Chromium Hydroxide

Review the current Safety Data Sheet and complete an appropriate risk assessment before handling Chromium Hydroxide. Wear suitable chemical-resistant gloves, safety goggles, and protective clothing. Avoid creating or inhaling dust and prevent contact with the eyes and skin. Use appropriate ventilation when necessary, prevent environmental release, and follow institutional procedures for spill response and chromium-containing waste disposal. Educational laboratory use requires suitable supervision and appropriate safety controls.
