Concept explainers
Interpretation:
The method to determine whether a compound is a hydrate or not needs to be explained.
Concept introduction:
Hydrate compounds have water of crystallization. Molecular water is incorporated in the structure of the compound.
Answer to Problem 178A
The change in structure on heating can help to determine whether a compound was hydrated or not.
Explanation of Solution
Overall structure of a hydrate largely depends on the number of water molecule incorporated.
When hydrate compounds are strongly heated, one by one all the water molecules are removed. As the structure is broken due to water loss, the appearance is changed. In most of the cases crystalline solids are converted to amorphous powder. For example sodium carbonate decahydrate when heated strongly it is converted to white amorphous powder.
Blue copper sulfate pentahydrate when heated strongly is converted to white anhydrous copper sulfate.
Thus, from color and appearance change it can be understood that a compound was hydrate.
Hydrates on heating might show color change along with change in appearance. This can help to determine whether a compound was hydrate.
