Determination of the Solubility of Calcium Hydroxide Apparatus 250 cm3 volumetric flask 25cm3 pipette Pipette pump Burette 250cm3 conical flask Small funnel Rubber bung White ceramic tile Burette clamp G clamp Lab stand Quantities to be used 25cm3 Hydrochloric acid solution @ 0.3moldm-3 225cm3 Distilled Water Excess Methyl Orange indicator Excess Calcium Hydroxide solution @ 0.015moldm-3 Excess distilled water (for washing glassware) Making the Hydrochloric acid solution The hydrochloric solution provided is of a very high concentration compared to the concentration of the calcium hydroxide. Because the ratio of moles of hydrochloric acid to calcium hydroxide is 2:1, the concentration of the hydrochloric acid must be about twice as much as the calcium hydroxide: Ca(OH)2(aq) + 2HCl(aq) --> CaCl2 + 2H2O No. of Moles 1 2 The hydrochloric acid provided is of very high concentration compared to the calcium hydroxide, and so this will cause a very high error. Diluting the hydrochloric acid will reduce the error, because more calcium hydroxide will be needed to be added to complete the titration,...
