Question

Why wouldn't you want to heat a crystal Hydrate to recover H2O?

I understand that some decompose under heat.

Some will form a different product, Such as CuSO4 becoming CuO if heated too much and we wouldn't recover all of the water.

Some, such as AlCl3 actually forms HCl instead of water and needs to be reacted with another compound first.

But what other reasons are there, specific to crystal hydrates? I need two reasons and I feel like I only have one so far.

Answer 1

Answer:

this experiment, an unknown ionic hydrate was heated in order break any bonds between water molecules and the salt's crystal lattice to recover the original salt. Then when given the molar mass of the unknown salt, the ratio of H 2 O to salt in the original hydrate was able to be figured out.
