Form – Crystalline powder
Grade – AR (Analytical Reagent)
Application – Oxidizing agent, glassware cleaning, analytical chemistry
Product Overview
Chromium (VI) oxide, commonly known as chromium trioxide (CrO₃), is a highly pure AR-grade chemical compound essential for laboratory applications requiring strong oxidizing properties. This crystalline powder, with a minimum purity of 99%, is widely recognized for its effectiveness in oxidation reactions, glassware cleaning, and as a reagent in analytical chemistry. Its hygroscopic nature demands careful handling and storage in a dry, well-ventilated environment to maintain stability. The compound’s high solubility in water makes it suitable for preparing chromic acid solutions, often used in cleaning and etching processes. Due to its corrosive and toxic properties, proper protective measures, including gloves, goggles, and lab coats, are mandatory during use. Chromium trioxide AR grade is a reliable choice for researchers and lab professionals seeking consistent performance in critical applications.
FAQs
1. What precautions should be taken while handling chromium trioxide?
Chromium trioxide is highly corrosive and toxic. Always wear protective gear like gloves, goggles, and a lab coat. Work in a fume hood to avoid inhalation, and ensure proper ventilation in the workspace.
2. Can chromium trioxide be used for cleaning laboratory glassware?
Yes, chromium trioxide is commonly used in chromic acid solutions for cleaning glassware. It effectively removes organic residues and stains, but handle with care due to its corrosive nature.
3. What is the shelf life of chromium trioxide AR grade?
When stored in a tightly sealed container in a cool, dry place, chromium trioxide AR grade can retain its purity for up to 2 years. Avoid exposure to moisture to prevent degradation.
4. Is chromium trioxide compatible with plastic containers?
No, chromium trioxide is highly corrosive and can react with most plastics. Always store it in glass or corrosion-resistant containers with secure lids.
5. What alternatives exist for chromium trioxide in oxidation reactions?
Alternatives like potassium permanganate or hydrogen peroxide can be used for certain oxidation reactions, but their effectiveness varies depending on the specific application and conditions.
