Let’s go step by step to solve this problem.
We’re looking at two lemonade mixtures in Model 1. Both pitchers have the same total volume of solution — 2 liters (as stated in the note). The difference is how much sugar (solute) is dissolved in each.
In Solution 1, there are fewer dots (which represent sugar molecules) floating around in the pitcher and glass.
In Solution 2, there are more dots — meaning more sugar is dissolved.
Now let’s answer each part:
---
1a. What is the solvent? What is the solute?
- Solvent = the substance that does the dissolving → here, it’s
water.
- Solute = the substance being dissolved → here, it’s
sugar (shown as dots).
✔ So:
Solvent:
water
Solute:
sugar
---
1b. Lemonade Solution 1 has (more/less/the same) volume of solution as Solution 2.
The note says: “Both pitchers were filled with enough water to provide 2 L of solution.”
That means both solutions have the
same total volume — 2 liters.
✔ Answer:
the same
---
1c. Lemonade Solution 1 has (more/less/the same) quantity of solute as Solution 2.
Looking at the pictures:
- Solution 1 has fewer dots (sugar molecules).
- Solution 2 has more dots.
So Solution 1 has
less solute than Solution 2.
✔ Answer:
less

2. List two ways to differentiate a concentrated solution from a dilute solution.
From the image and context:
- Concentrated = more solute per volume → darker color (if colored), sweeter taste (for lemonade).
- Dilute = less solute per volume → lighter color, less sweet.
The student already wrote a good answer:
> Visually: the more concentrated solution will have a deeper color. Taste! The more concentrated solution will have a sweeter (in this case) taste.
That’s correct and matches what we see.
✔ Two ways:
1.
Color intensity – concentrated looks darker or richer.
2.
Taste – concentrated tastes stronger/sweeter (for lemonade).

Final Answer:
1a. Solvent: water; Solute: sugar
1b. the same
1c. less
2. Visually: concentrated solution has deeper color; Taste: concentrated solution tastes sweeter
