Calcium Carbonate Extra Pure
Calcium Carbonate Extra Pure is a high-purity, fine white powder widely used in laboratory settings as a buffering agent, a source of calcium ions, and a standard for acid-base titrations. It plays a key role in chemical analysis, gravimetric studies, and as a neutralizing agent in various reactions. In educational and research laboratories, it is also used to demonstrate decomposition reactions upon heating, releasing carbon dioxide and forming calcium oxide. The extra pure grade guarantees minimal impurities, making it suitable for precise analytical applications. It should be stored in tightly sealed containers in a dry environment to maintain its stability and reactivity.
Marble Chips Extra Pure
Marble Chips Extra Pure are high-grade, naturally occurring calcium carbonate fragments that have been carefully processed to ensure exceptional purity. These white or off-white chips are widely used in laboratory experiments, especially in demonstrations involving acid-carbonate reactions where the release of carbon dioxide is observed. Beyond educational and research use, they also serve as a buffering agent, filtration medium, and mild abrasive in various industrial applications. Due to their chemical stability and high calcium content, marble chips are ideal for use in controlled environments where contaminants must be minimized.
