Homework Statement



I have a lab to complete, but I can't produce a reasonable hypothesis. This is the information I'm given to base my hypothesis on.

Homework Equations



In this experiment, you will empirically determine the ratio of water to salt in the hydrates copper sulfate hydrate (CuSO4*XH2O) and magnesium chloride hydrate (MgCl2*XH2O). The symbol X in the formulas represent the unknown number of water molecules.

The formula for the hydrate gives the number of water molecules in the hydrate per molecule of salt. Your experimental measurements will be converted to a molar ratio, that is, the ratio of moles of water to moles of the salt in the hydrate in order to find a value for X.


The Attempt at a Solution



I understand what my goal is and how I'm going to be getting there, but I can't think of a prediction in an "if-then" format.

Can you give examples of prediction in the "if-then" format?

sure, an example would be something like:

If red and blue is mixed, then the resulting color will be purple.

I hope that was an adequate example.

This is prediction, not hypothesis.
