Solubility

Question 2 • AA-F26 Physical Science

Maceo is making rock candy. Which best describes the steps she should take?

Answer
A
heat a saturated sugar water solution, dissolve more sugar, then let the solution cool
B
heat a saturated sugar water solution, dissolve more sugar, and wait until the water evaporates
C
saturate a water solution, increase the pressure, and dissolve more sugar
D
saturate a water solution, lower the pressure, and dissolve more sugar

Explanation

Heating the saturated sugar-water solution lets it dissolve additional sugar, creating a solution that holds more sugar than it can at room temperature. As the solution cools, the extra sugar comes out of the solution and forms crystals on the candy stick. This is why letting the solution cool is the best choice for making rock candy.
