Calcium hydroxide can be made from limestone by heating the limestone (calcium carbonate) while heating the carbon dioxide is given off . this turns the limestone into calcium oxide and now if you add a little water the calcium oxide will turn into calcium hydroxide Hope it helped you....:) The process can be shown in a flow diagram called the 'limestone reaction cycle'
Take water in a beaker. Add sodium carbonate to it and stir till sodium carbonate dissolves. However for scientific or any practical purpose, take a fixed weight of sodium carbonate and dissolve in a definite volume of water and calculate the concentration in terms of molarity or weight per volume etc.
Sodium carbonate does not decompose at room temperature...
A Maalox tablet is made out of calcium carbonate. One tablet will move the pH of a stomach from about pH 6 to pH 8.
To determine the volume of carbon dioxide needed, you would need to know the stoichiometry of the reaction between carbon dioxide and calcium carbonate. In this case, since 20 grams of calcium carbonate is given, you would convert that to moles using the molar mass of calcium carbonate. Then, using the balanced equation, you can determine the mole ratio between carbon dioxide and calcium carbonate. Finally, using the molar volume of carbon dioxide gas at the given conditions (usually 22.4 L/mol at standard temperature and pressure), you can calculate the volume of carbon dioxide needed.
Calcium carbonate is not soluble in water.
Calcium hydroxide can absorb carbon dioxide and become calcium carbonate; by heating calcium carbonate is transformed in calcium oxide. The time for these reactions depends on the temperature, pressure, volume of the reactants, amounts of reactants, the physical appearance, sometimes stirring etc. Please read a chemical kinetics book for more details and understanding of the chemistry.
Volume mL= 32.76 mL x 0.0215 M/ 0.03455 = 20.386 mL calcium hydroxide solution.
