Question
In the diagram below, one beaker contains pure water and the other contains an equal volume of seawater. Seawater has various salts dissolved in it. The beakers are sitting in a totally enclosed chamber, and the outside temperature and pressure are held constant. Identify the statements below about this situation that are not correct.
I. Water will be transferred from the pure water beaker to the seawater beaker.
II. The vapor pressure of the seawater is higher than the vapor pressure of the pure water.
III. Pure water evaporates at a faster rate than seawater.
IV. Water in the gas phase condenses into the seawater beaker at a faster rate than into the pure water beaker.
Choose NOT CORRECT options.
Pure water seawaterExplanation / Answer
From Raoult's law, we can say that vapor pressure of pure water is higher than the vapor pressure of
seawater. So, statement II is not correct
Water in gas phase condenses into seawater beaker at a slower rate than into the pure water beaker,
sea water has salts, therefore it takes time to evaporate as well as condense. Statement IV is also
not correct.
II & IV are not correct
