What Dissolves in Water?

Author(s): Nancy P. Moreno, PhD, Barbara Z. Tharp, MS, and Judith Dresden, MS.

What Dissolves in Water?

This activity uses guided inquiry to examine one of the unique physical properties of water, its ability to dissolve many different substances. Students will investigate whether several common substances are soluble in water, make and record observations, measure and draw conclusions about solubility. 

Concepts

  • Some liquids and solids will dissolve in water. They are soluble. 
  • Substances dissolved in water sometimes appear to be invisible or disappear into the solution. 
  • A solution is a liquid mixture in which the minor component (the solute) is uniformly distributed within the major component (the solvent).
