Question

Why Efflorescence is minimum during humid conditions?​

Answer 1

Answer:efflorescence is the phenomenon by which a salt or a substance loses its water of crystallization to the atmosphere. Now when atmosphere is dry the efflorescence will be very high for the air can absorb much moisture, but in case of humid air it is slow ,for the atmospheric air already contains moisture . Thus if air is humid the efflorescence of a salt or a substance is low

Explanation:hope it helps

Answer 2

Answer:

It occurs when vapour pressure in the hydrated crystal s exceeds atmospheric vapour pressure
