Answer:
colloidal sollution is a chemical change
The spelling of de the spelling of deliquescence is wrong.
A chemical change is a permanent change in which the original substance gives rise to one or more substances with different properties.
The phenomenon in which a crystalline hydrated Salt, on exposure to the atmosphere, loses partially are completely its water of crystallization is called eflorescence.
The phenomenon in which a water soluble substances, on exposure to atmosphere at ordinary temperature absorbs moisture from the atmosphere, becomes moist and finally dissolves in the absorbed moisture to form a saturated solution, is called deliquescence.
A solution is said to be a saturated solution at a particular temperature if no more of the solute can be dissolved in it at the temperature is called saturated solution .
