Sugar and Salt Solutions PhET – Introduction to Solutions
Goal: you will be able to
1). Compare and contrast the behavior of molecular compounds and chemical salts in water.
2). Provide evidence to classify molecular compounds and chemical salts as either as
electrolytes or nonelectrolytes
3). Draw particle diagrams that represent aqueous solutions of chemical salts in water and
molecular compounds in water
4). Propose an explanation of the behavior of the conductivity tester in the salt and sugar
solutions.

● Take a moment to play with the controls before moving on to the procedure!
● Select the Reset All button before proceeding
Procedure
● Make sure the solute is selected to salt
1). Pick up the conductivity tester and place it in the water in the beaker. Record your initial
observations of the behavior of the light bulb in the water.
Nothing is happening to the light bulb
2). Do 1 shake of salt into the water. What do you observe about the light bulb?
