Andrea Kam Lab #3 Questions 1. Differences in the two calcium carbonates: - Destab 95 o Static charge: reduced compared to precipitated calcium carbonate o Particle size: particles are more uniform and larger o Flowability: free-flowing powders o Bulk density: heavier than precipitated calcium carbonate compared to precipitated calcium carbonate (0.95-1.34 gms/ml) - Precipitated calcium carbonate o Static charge: greater compared to Destab 95 o Particle size: particle sizes are smaller, irregular and rhombohedral in shape compared to Destab 95 o Flowability: The particles are very sticky and it does not have good flow o Bulk density: lighter than Destab 95 (0.4 to 0.9 gms/ml) 2. Hand filling capsules: Prefer precipitated calcium carbonate because it is more cohesive than the Destab 95. Hence, it will be easier to pack into the capsules. Machine filling capsules: Prefer the precipitated calcium carbonate because you need 25 grams of calcium carbonate in order to make 100 capsules, if you used Destab 95, which only contains
