EXPERIMENT 7: DETERMINATION OF THE Ks OF A SLIGHTLY SOLUBLE COMPOUND Date: Name: Instructor Post-Lab Questions (Turn in to your Instructor with the post laboratory report for this experiment.) 1. The literature value for the K, of Ca(OH), at 25 'C is 4.68 x 10*. How does the value you determined in the lab compare with this result? Explain what may have caused your result to differ from this value. (Clearly explain what may have happened. Should you have obtained the literature value? Clearly explain how this could have happened.) How would your results have changed if there had been a trace of basic (hydroxide containing) impurity present in the Erlenmeyer flasks you used? 2. eerimest 7 | Determination of theofa Slightly Seluble Compounte
