Ksp of Ca(IO3)2 lab questions 1) Why is it necessary to filter the calcium iodate solution through dry filter paper, without adding any water? 2) If water had been added during the filtration process, how would this affect your calculated value for the Ksp of calcium iodate? Clearly explain whether your value would be too high or too low compared to the actual Ksp and why.

Question Completion Status: QUESTION 1 Why don't you have to accurately record the amount of Ca(OH)2 used in the saturated solution? The Ca(OH)2 only serves as the spectator ions in this experiment. The amount or concentration of Ca(OH)2 is not important in this experiment. We are only interested in the amount of Ca(OH)2 that dissolves at each temperature (which is found after filtration via titration), and not the entire amount of Ca(OH)2 that is used in the saturated solution before...
