Determination of the solubility of calcium hydroxide I have been given a sample of calcium hydroxide and have to find the solubility of the sample. When dissolved in water it forms an alkali solution so the method I will be using is an acid-alkali based titration. The acid I am using will be hydrochloric acid. Equation- Ca(OH) + 2HCl CaCl + 2H O Apparatus- I want to use apparatus with a low percentage error to enable my results to be as accurate as possible and also use realistic measurements of the solutions that I will be using in my experiment. Concentration of acid- Using the balanced equation you can see that the ratio between calcium hydroxide and hydrochloric acid is 1:2. We already know the approximant concentration of Ca(OH) and the concentration of hydrochloric acid. These are 0.015 mol dm and 0.300 mol dm . At these concentrations the ratio is 1:20 so the hydrochloric acid...
