Find the solubility of Ca(OH)2Objective:----Determine the solubility of Ca(OH)2.To achieve the purpose of this experiment the experiment it must be planned and carried out. I was informed that the solubility of Ca(OH)2 is between 1 and 1.5 g per dm3. I am also provided with a standard 1M hydrochloric acid (HCl) solution which may need to be diluted to meet the measurement needs of the experiment. Equipment:[IMAGE]* 1 g of Ca(OH)2.* Pipette 25 cm3* 2 beakers of 500 cm3* Conical flask 250 cm3* Burette* White tile* Burette stand* Stand* Indicator* 300 cm3 of standard solution of hydrochloric acid (0.05 M concentration)* Distilled water* Filter paper* Stirring rod* FunnelMethod:* Add 1 g of Ca(OH)2 to 300 cm3 of distilled water in a 500 cm3 beaker. Continue stirring the solution until the solid stops dissolving. This results in a saturated solution.* Filter the excess solid into another 500 cm3 beaker using moist filter paper (distilled water).* Repeat filtering the solution until no solid remains. Making sure to mix the solution between each filtration and clean the other glass with plenty of water.* There should be 300 cm3 of saturated Ca(OH)2 solution left which will be used in the titration experiment needed to find the concentration of the solution.* Use some Ca(OH)2 to rinse the conical flask and pipette. Use a little HCl to rinse the burette.
