Cobalt(II) chloride is a salt that loses its color when heated. It typically appears blue in its hydrated form, but upon heating, it loses water and turns into a pink anhydrous form. This color change is due to the loss of water molecules that are part of its crystal structure.

What is the term a hydrate with the water heated off?
Anhydrous is the term for a hydrate with water heated off. when a hydrated salt is heated, it loses water of crystallization leaving an anhydrous salt.
What is observed when Fe2SO4 and FeSO4.7H2O are heated strongly?
When FeSO4·7H2O is heated strongly, it loses its water molecules and forms anhydrous FeSO4. The color changes from blue to white or pale green due to the removal of water molecules, and the compound becomes anhydrous iron(II) sulfate (FeSO4).
When zinc carbonate is heated on a dry test tube what observation is seen?
when zinc carbonate is heated it' white colour changes to yellow . And when it is cooled it again changes to it original colour
Why does salt pop when heated?
When salt is heated, the moisture inside it evaporates quickly, causing the salt to crack and pop. This happens because the rapid release of steam generates pressure within the salt crystals, leading to the popping sound.
What would happen if salt water is heated?
Eventually if heated long enough (and hot enough) all the water would either eat the world or MELT (turning into steam), leaving behind nothing but solid salt behind. This is one way that you can remove salt from sea water in fact.

What is the decomposition equation for Epsom salt?
The decomposition equation for Epsom salt (magnesium sulfate heptahydrate) is: MgSO4·7H2O -> MgSO4 + 7H2O. When heated, Epsom salt loses its water molecules, leaving behind anhydrous magnesium sulfate.
