In Aquarium C, would the water level on the side with 30% solution of NaCl be higher, lower, or equal to the water level on the side with 5% solution? Explain

In Aquarium C, the water level on the side with 30% solution of NaCl will be higher than the water level on the side with 5% solution.

Explanation:

The movements of molecules based on differences in concentrations of these molecules in different regions is explained by the phenomena of diffusion and osmosis.

Diffusion is the movement of moleculesmfrom regions of higher concentrationto regions of lower concentration until equilibrium concentration is attained.

Osmosis which is a special form of diffusion involving water molecules is the movement of water molecules in a solution across a semipermeable memebrane, from regions of high solvent concentration (low solute concentration) to regions low solvent concentration (high solute concentration) until equilibrium is attained.

A 30% solution of NaCl is more concentrated than a 5% solution of NaCl, therefore, water molecules will move across the semipermeable from the 5% solution to the 30% solution. This will result in a rise in the water level in the 30% solution.

Thus in Aquarium C, the water level on the side with 30% solution of NaCl will be higher than the water level on the side with 5% solution.
