CaO H2O Ca(OH)2.HCO3 is known as the bicarbonate ion. Calcium bicarbonate is many times more soluble in water than calcium carbonate -- indeed it exists only in solution. Giant Explosion, CaO H20, QuickLime and Water, Easy Experiement to do at home science experiement - Duration: 1:13.Make Calcium Hydroxide - Ca(OH)2 from Plaster of Paris - Duration: 6:01. one mol of CaCO3 (100 g) and contains 2 x 61 g 122 g of HCO3- and the conversion is as follows: Bicarbonate Alkalinity as HCO3- (mg/L) 1.22 BicarbonateConsider the following reactions of CaCO3 and hydroxide ions with protons (acid): CaCO3 2 H Ca2 H2CO3 2 OH- 2 H 2 CaO H2O Ca(OH)2.CaCO3 CaO CO2. CaCO3 also releases carbon dioxide when it is reacted with acids. Calcium carbonate reacts with water containing carbon dioxide to form the water soluble calcium bicarbonate salt ( Ca(HCO3)2). Note: lime (CaO or Ca(OH)2) is a natural plasticiser and 100 cementitious.Recall that the presence of calcium hydrogen trioxocarbonate(IV), Ca(HCO3 )2, is the cause of temporary hardness in water. M(OH)2(s) water ———> M2(aq) 2OH(aq).
