Respuesta :

The required "option b) is not true about a hydrate".

Explanation:

  • The Residue of hydrate is insoluble so as to filter it out.
  • The Presence of hydrated water may evaporate during heating of the residue.
  • During dehydration, there is a color change that is when water is given off.
