Determining the Concentration of Limewater In order to find the concentration of calcium hydroxide solution I would carry out a titration. Titration is an example of volumetric analysis. Titration is a technique used to find the concentration of an unknown solution. Using volumetric analysis I can find the concentration of calcium hydroxide if the concentration of the acid is known. Calcium Hydroxide (Ca(OH)2) is formed when calcium oxide reacts with water. This reaction is exothermic and the product is slightly alkali. CaO(s) + H2O(l) Ca2+(aq) + 2OH-(aq) Calcium Hydroxide solution is called limewater. Limewater is formed when calcium carbonate (CaCO3(s)) is heated to form calcium oxide or quicklime (CaO(s)) and carbon dioxide (CO2(g)). Which is then reacted with water to form calcium hydroxide or slaked lime (Ca(OH)2(s)), this is then dissolved in water to form an aqueous solution of lime water (Ca(OH)2(aq)). I will write the symbol equation...
