What three changes do a hydrate undergo upon heating?

Answer 1

Normally heating a hydrate drives of water (as vapor) thus the mass of the substance being heated will be less at the end of the heating.

Answer 2

1) Change of color due to loss of water

2) Change in crystal structure due again to loss of water. 3) Dissolve in the hydrates own water of crystallization as the crystal form breaks down.

Answer 3

Sometimes yes, sometimes no. Copper sulfate pentahydrate is blue and the anhydrous form is white, so there is a color change. Magnesium sulfate anhydrous is pretty much the same color as the hydrated form, so here there is no color change.

Answer 4

Upon heating, a hydrate undergoes three changes:

1. Loss of water molecules through dehydration.
2. Changes in color and/or texture.
3. Possible decomposition or formation of a different compound.

Answer 5

When a hydrate is heated, the water, h20 is evaporated, leaving only the anhydrous salt. If you add water to a anhydrous salt, it will transition back into a hydrate.

Answer 6

When a hydrate is heated, the water, h20 is evaporated, leaving only the anhydrous salt. If you add water to an anhydrous salt, it will transition back into a hydrate.

Answer 7

A hydrate loses water on heating to become anhydrous

Answer 8

The water is lost to obtain the anhydrous salt.

Answer 9

It gets hot. Would you care to elaborate on the precise conditions (isobaric, constant volume, etc.)?

Answer 10

They get written down in what are universally regarded as some of the most boring books in all of creation.
