Chapter 8, Problem 19A

Interpretation Introduction

Interpretation : The term strong base is to be defined and they are also strong electrolytes or not is to be stated.

Concept Introduction : A substance that dissolved in a solution and dissociate into cations and anions is defined as an electrolyte. These ions comprise the property of conducting electricity. The strength of an electrolyte relies upon its capacity to dissociate.

Answer to Problem 19A

A strong base is a substance that completely dissolves in water to give hydroxide ions $\left({\text{OH}}^{-}\right)$ . Yes, strong base is also a strong electrolyte.

Explanation of Solution

A strong base is a substance that completely dissolves in water to give hydroxide ions $\left({\text{OH}}^{-}\right)$ . For an example, sodium hydroxide, the reaction is as follows.

  $\text{NaOH}\left(\text{l}\right)\stackrel{{\text{H}}_{\text{2}}\text{O}}{\to }{\text{Na}}^{+}\left(\text{aq}\right)+{\text{OH}}^{-}\left(\text{aq}\right)$

A substance that dissolves completely into its ions is also defined as strong electrolyte. Therefore, strong base is also a strong electrolyte because it dissociates and forms cation and anion.

Conclusion

A strong base is a substance that completely dissolves in water to give hydroxide ions $\left({\text{OH}}^{-}\right)$ . Yes, strong base is also a strong electrolyte.
