Chapter 22, Problem 13STP

To determine

To Describe:The result of adding $\text{NaCl}$ to the beaker.

Explanation of Solution

Introduction:

It is due to the absence of ions in the water, that the apparatus does not conduct current and the lightbulb does not glow.

When $\text{NaCl}$ crystals are added to the beaker and stirred, it dissociates to produce ${\text{Na}}^{+}$ and ${\text{Cl}}^{-}$ ions. These ions in the aqueous solution conducts electricity and the lightbulb glows.

Conclusion: The addition of $\text{NaCl}$ to the water in the beaker,conducts electricity in the setup and the lightbulb glows.
