Answer
Strong electrolytes completely ionize in water and produce a strong current. Ex. NaOH, HBr
Weak electrolytes partially ionize in water and produce a weak current. Ex.HF, HCN
Nonelectrolytes do not ionize in water and produce no current.
Sugar ($C_{12}H_{22}O_{11}$)
We may test the type of electrolyte by dissolving the substance in water and testing its conductivity and strength of the current produced by the brightness of a light.
Work Step by Step
Electrolytes are substances that when dissolved in water, produce a current. On the other hand, nonelectrolytes do not produce a current when dissolved in water. Strong electrolytes are primarily composed of strong acids, strong bases, and soluble salts which completely ionize and produce a strong current. Weak electrolytes are primarily weak acids and bases who partially ionize in water (<5%) and produce a weak current.
