Calcium carbonate
Product Overview & Quality
- Product Name: Calcium carbonate (Limestone / Calcite)
- Brand: Kemaus (Product Code: KA-126)
- Grade: Laboratory Grade (Lab Grade) with a dependable purity of 98.5 percent or higher. Manufactured under Kemaus standard laboratory quality control protocols to guarantee premium physical uniformity and low trace chemical background. Excellently suited for academic science experiments, acid neutralization workflows, and industrial R&D product formulations.
- Physical Properties: Odorless, tasteless, fine white powder or chalky white powder.
- Solubility: Practically insoluble in water and alcohol; dissolves readily and effervesces strongly in dilute acidic solutions (such as hydrochloric acid), liberating carbon dioxide gas.
- Key Use: Widely utilized as a core reactant in general academic and school chemistry laboratories for demonstrating acid-base reactions and gas generation. Commonly applied as an effective neutralizing agent to neutralize acidic chemical wastes or adjust solution conditions. Used as a high-purity calcium precursor for synthesizing specialized chemical derivatives, and functions as a standard structural filler in pharmaceutical, cosmetic, polymer, and coating formulation research.
Safety & Hazards
- Classification: Not classified as a hazardous substance according to GHS regulations. It features an exceptional non-toxic chemical profile and is benign to biological tissues. Acts as a mild physical and mechanical dust irritant.
- Health Risks: Direct eye contact with large amounts of fine powder triggers temporary mechanical irritation, watering, or short-term redness. Inhalation of airborne particles may induce coughing or sneezing.
- First Aid Measures: Flush eyes immediately with plenty of flowing water. Wash affected skin with soap and water. Seek medical advice if irritation develops or persists.
Handling & Storage
- Storage: Store in the original, tightly sealed Kemaus container. Keep in a cool, dry, and well-ventilated space at stable room temperature (below 30 degrees Celsius). Extremely stable under normal environmental storage conditions, but shield from high ambient humidity to prevent physical caking or clumping. Keep strictly separated from strong acids.
- Precautions: Wear standard personal protective equipment (PPE), including laboratory gloves, safety glasses, and a particulate dust mask. Secure the container cap tightly immediately after each use to preserve the dry integrity of the powder.
