Question

in surface area, addition of common Salt
if surface area of liquid is large then evaporation will be
a. more
b. moderate
c.more
d.none of the above​

Answer 1

Higher the exposed surface area of water, higher will be the evaporation. When common salt is added to water then surface is occupied by the solvent as well as non-volatile solute particles. So, the escaping tendency of solvent particles decreases and thus the evaporation of water decreases.

Answer 2

Answer:

b.moderate.
