Question

Mrs. Rogers was making Kool-Aid for her grandson. She knows that her grandson does not care for very sweet drinks, so she only adds 1/2 cup of sugar instead of the 1 cup the package instructions calls for. When Mr. Rogers goes to drink some of the Kool-Aid, he does not think it tastes "right." Using your knowledge of concentrations, explain to Mr. Rogers why Mrs. Rogers' Kool-Aid would not meet his taste expectations.

A. The Kool-Aid is supersaturated because there is too much sugar, or solute, in the solution.
B. The Kool-Aid is saturated because there is just the right amount of sugar, or solute, in the solution.
C. The Kool-Aid is unsaturated because there is less than the recommended amount of sugar, or solute, in the solution.
D. The Kool-Aid is saturated because the amount of powder added did not change.

Answer 1

Mrs. Rogers made the Kool-Aid unsaturated by adding only half the recommended sugar, leading to a Kool-Aid mixture with less sweetness than the standard, which explains why Mr. Rogers finds the taste to be 'not right'.

Step-by-step explanation:

Mr. Rogers, the reason the Kool-Aid does not taste 'right' to you is likely due to the difference in sugar concentration that Mrs. Rogers used. The package instructions called for 1 cup of sugar, which gives a certain expected sweetness and flavor profile. Since Mrs. Rogers only added ½ cup of sugar, the resulting Kool-Aid is unsaturated with sugar compared to the standard recipe, essentially having a lower solute concentration. This means there is less sugar dissolved in the Kool-Aid than what the water can potentially dissolve, giving it a less sweet taste than you might expect.
