Question

1. compare the concentration of solute in the first test tube on the left to the last test tube on the right. all the test tubes below contain the same substance. which statement is correct? a. concentration is the same in both. b. the first test tube has a higher concentration. c. the last test tube has a higher concentration. d. both test tubes have no solute. 5. jordan poured a drink of purple kool - aid and added ice to it while watching a movie. unexpectedly, he had to leave for 20 minutes. in terms of solute, solvent, dilution, and concentration, explain what is occurring in the glass during those 20 minutes.

Explanation:

Step1: Observe test - tube darkness

Darker color indicates higher concentration. First tube is darker.

Step2: Analyze ice - melting in drink

Ice (solvent) melts, increasing volume, diluting solute (flavor, color, sugar), decreasing concentration.

Answer:

1. B. The first test tube has a higher concentration
2. Ice (solvent) melts, diluting solute, decreasing concentration.
