Introduction

Have you ever added a spoon of sugar to your tea and wondered why it disappeared? Where did it go? The sugar did not actually disappear—it changed from its solid form into a dissolved form in a process called chemical dissolution. The result is a tea-sugar mixture in which individual sugar molecules become uniformly distributed in the tea. But what happens if you increase the amount of sugar that you add to your tea? Does it still dissolve? In this science activity, you will find out how much of a compound is too much to dissolve.

  • Glasses or cups, 8 oz. (8)
  • Spoons (4)
  • Measuring spoon (1 teaspoon)
  • Epsom salt (150 g)
  • Table salt (50 g)
