Essay / Find the solubility of Ca(OH)2 - 642
Find the solubility of Ca(OH)2Objective:----Determine the solubility of Ca(OH)2.To achieve the aim of this experiment, a l The experiment must be planned and carried out. I am given the information that the solubility of Ca(OH)2 is between 1 and 1.5 g per dm3. I am also given a standard solution of 1M hydrochloric acid (HCl) which may need to be diluted to meet the measurement needs of the experiment. Apparatus: [IMAGE]* 1 g of Ca(OH)2.* Pipette 25 cm3* Beaker 2 x 500 cm3* Conical flask 250 cm3* Burette* White tile* Burette stand* Stand* Indicator* 300 cm3 hydrochloric acid standard solution (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 to stir the solution until the solid stops dissolving. This leaves a saturated solution.* Filter the excess solid into another 500 cc beaker using damp filter paper (distilled water).* Repeat filtration of the solution until it no longer contains remains more solid. Be sure to stir the solution between filtrations and clean it. the other beaker with plenty of water.* This should leave 300 cm3 of saturated Ca(OH)2 solution which will be used in the titration experiment needed to find the concentration of the solution.* Use a little Ca(OH)2 OH)2 to rinse the conical flask and thepipette. Use a little HCl to rinse the burette.
