Two equally sized beakers are filled with the same volume of two different liquids. Beaker A contains 100mL water. Beaker B contains 100mL of a 3M solution of sodium chlorode in water. Upon standing at room temperature, which of the two liquids will evaporate first? Please explain.
Homework Answers
Water is a volatile liquid. And 3M sodium chloride in water has non volatile solute i.e. NaCl dissolved in water whichever decreases its evaporation.
The salt molecules block the evaporation of water by utilising its surface area , and hence it will evaporate slower than beaker containing fresh water.
So beaker A will evaporate first.

Two 1-L beakers, A and B, each containing a different aqueous solution of urea (a nonvolatile nonelectrolyte with MW = 60.06 g/mol) are placed together in a box, which is then sealed. The temperature remains constant at 20 °C. Initially, there is 270 mL of solution in A and 690 mL of solution in B. As the solutions stand in the sealed box, their volumes change slowly for a while. When they stop changing, beaker A contains 490 mL and...
