Question

A

B

Two solutions can be in equilibrium

with one another.

What does this mean?

The concentration in both solutions is the

same.

The concentration in both solutions is

different.

Answer

Both solutions have the same concentration, but different concentrations from each other.

When two solutions are in equilibrium with each other, it means that they have the same concentration of solutes, but the concentration of solutes in each solution may be different. This can occur when two solutions are separated by a semipermeable membrane, and the solutes are able to move freely between the two solutions until their concentrations become equal. At this point, the solutions are said to be in equilibrium with each other.
