 OBJECT: To prepare and submit magnesium carbonate (MgCO3) . REFERENCE  1. Singh H.R., Kapoor V.K. “Practical Pharmaceutical chemistry”, Vallabh Prakashan, Ed I st, 2008, pp 23-24.  2. Chatwal G.R, “Pharmaceutical chemistry inorganic” Himalaya publishing house, Ed 5 th, 2010, pp 164-165. REQUIRMENTS  Chemical required:  Magnesium sulphate(MgSO4), Sodium carbonate (Na2CO3)  Apparatus required: - Beaker, glass rod, measuring cylinder, funnel.  THEORY  Synonyms: Epsom salt Chemical formula: MgCO3  Molecular weight: 84.31  Magnesium carbonate is hydrated basic magnesium carbonate containing the equivalent of 40-50% of magnesium oxide. It occurs in two form, light and heavy magnesium carbonate. Dosage form is in form of oral suspension, tablets (200mg). Heavy Magnesium carbonate is different from light magnesium carbonate in density. 15g of heavy magnesium carbonate occupies a volume of 30 mL while light Magnesium carbonate occupies a volume...

 EXPERIMENT OBJECT: To prepare calcium carbonate (CaCO3).  REFERENCES 1. Singh H.R., Kapoor V.K. “Practical Pharmaceutical chemistry”, Vallabh Prakashan, Ed. I st, 2008, pp 109.  2. Chatwal G.R, “Pharmaceutical chemistry inorganic” Himalaya publishing house, 5th Ed. 5th, 2010, pp 161-163.  REQUIREMENTS  Chemical required: Sodium carbonate (Na2CO3), Calcium carbonate (CaCl2)  Apparatus required: Beaker, funnel, glass rod & Measuring cylinder.  THEORY   Synonyms: Precipitated Chalk  Chemical formula: CaCO3  Molecular weight 100.09  It has been regarded as one of the most abundant and widely distributed calcium salts. Calcium carbonate is found in nature as limestone, chalk, marble, argnite, and calcite and one of the main constituents of pearls and shells. It is a fine white odorless, tasteless microcrystalline powder. It is practically insoluble in water but its solubility is increased by the presence of any ammonium salts or c...
