The compound that produce the bright light in the conductance apparatus should be identified. Concept Introduction: Conductivity of electricity is a physical property which is typical of species when dissolved in solution, typically, in an aqueous solution. If the material dissolves properly in water, and conduces electricity, then this is said to be a strong electrolyte. A material which dissolves and only conduces a small amount, will be considered a weak electrolyte. A material which will not conduct electricity at all is considered a nonelectrolyte. Note that sucrose is not even an electrolyte, so ignore it, as it will not conduct electricity.

Interpretation Introduction

Interpretation:

The compound that produce the bright light in the conductance apparatus should be identified.

Concept Introduction:

Conductivity of electricity is a physical property which is typical of species when dissolved in solution, typically, in an aqueous solution.
