in the determination of the empirical formula of a hydrate lab, it is realized that some of the contents of the crucible remained blue. would this cause the z and y values to be erroneously high or low?
Homework Answers
No, this would not cause Z and Y values to be erroneously high or low. It will cause a little shift the value towards low. As water molecule is present everywhere, some of the dehydrated species will lower the value by very very less magnitude.
