Does adding boiled, deionized water to the titrating flask to wash the wall of the Erlenmeyer flask and the buret tip affect the Ksp value of the Ca(OH)2? Explain.
Homework Answers
Because the indicator is unaffected. The indicator will change
colour once the amount of chemical from the burette is added
sufficient to reach an equivalence point. Boiled deionized water
only dilutes the mixture, it doesn't change the amounts of either
reagent.
Ksp is temperature dependant. If you look at the list of Ksp values you should always see a note specifying that these values are determined at 25
