Description: A mixture of potassium and sodium chlorides melts over a Meker burner. The lightbulb conductivity tester can be used to show that solid does not conduct, but liquid does. The particles (ions) must therefore be charged.

This demonstration is also available on video and JCE "Chemistry Comes Alive!" Vol. 1 CD-Rom.
