Question

Do hydrated salts appear moist when touched?

Answer 1

1. Hydrated Salts are the salts which contain water of crystallization are called hydrated salts.
2. Water of Crystallization: Some salts have an affinity to water and the water molecules get trapped in the crystal lattice, these water molecules are called water of Crystallization.
3. Hydrated salts do not appear moist when touched because the water molecules are trapped inside the crystals and not in their liquid form.

Hence, No, hydrated salts do not appear moist when touched.
