Question

Which line in the graph represents the bag that contained a solution isotonic to the 0.6 M solution at the beginning of the experiment?

A) A
B) B
C) C
D) D
E) E

Answer 1

The line that represents the bag containing a solution isotonic to the 0.6 M solution at the beginning of the experiment is line C (option C).

Step-by-step explanation:

In an experiment involving solutions of varying concentrations, an isotonic solution is one that has an equal osmotic pressure compared to another solution. In this context, the line on the graph depicting an isotonic solution to the initial 0.6 M solution would be the line where the concentration intersects with the initial 0.6 M concentration line. Among the options provided (A, B, C, D, E), line C intersects or crosses the 0.6 M concentration line, signifying it as the bag containing a solution isotonic to the initial 0.6 M solution at the start of the experiment (option C).

The concept of isotonicity in solutions involves finding the equilibrium where the solute concentrations are equal inside and outside a cell or bag. In this experiment, the bag with a solution represented by line C exhibits a concentration where it intersects with the initial 0.6 M concentration line, indicating an equal osmotic pressure compared to the initial solution. Therefore, line C is the representation of a solution that is isotonic to the 0.6 M solution at the experiment's onset, according to the graph provided.
