Question
Chapter 18, Problem 18.42P
Interpretation Introduction
Interpretation: To explain the meaning of the word “strong” for acids and bases and also the reason behind the ranking of strong acids and strong bases as strong electrolytes.
Concept introduction: Acid will have the ability to donate a proton and the base will have the ability to accept the proton. Acids and bases will be classified as strong or weak depending on their degree of dissociation. Both acids and bases will act as electrolytes. An electrolyte is a substance that dissociates as ions in the aqueous solution. Therefore, the strength of an acid and a base will co-relate with the electrolytic strength.
