Question

state the method by which hydrated salt can be anhydrous​

Answer 1

$\mathbb{\huge{\pink{ANSWER}}}$

Often, a hydrated salt can be converted into an anhydrous salt (one without water) by strong heating to drive off the water molecules. The mass of the hydrate will differ from the mass of the anhydrous salt by the mass of water that was removed during heating.
