Answer:
The solution is hypotonic
Step-by-step explanation:
Molecules in a solution move from highly concentrated regions to regions of low concentration in an effort to reach a state of equilibrium- where the molecules are equally distributed. This always occurs with the molecules moving down the concentration gradient.
Solutions can be:
- hypertonic, or more concentrated;
- hypotonic- less concentrated
- isotonic- same concentration
At 40% salt concentration, solution A is hypertonic while the less concentrated solution at 0% salt concentration is hypotonic.
