Document Summary
Date the experiment was performed: november 23th, 2015. Date the lab report was submitted: december 3th, 2015. Calcium hydroxide ca(oh)2 also called slaked lime is produced by reacting lime cao with water in a process called slaking1. Since ca(oh)2 is a strong base, it can decompose to ca+2 and oh- To determine the hydroxide concentration in the solution, titration can be performed with hcl. The concentration of acid will equal the concentration of base at equivalence point; when the solution with the phenolphthalein blue indicator turns clear when equivalence point was reached. Calcium hydroxide acts differently in different conditions so properties of this compound will be determined and compared at different temperatures; room temperature 20. 1 c, 20. 9 c, 63. 4 c and at boiling temperature 100. 3 c. The purpose of this experiment is to calculate the solubility of ca(oh)2 using the equation ksp = [ca2+][oh-]2 (2) at different conditions.
