Question
Chapter 4, Problem 4.17P
(a)
Interpretation Introduction
Interpretation:
Potassium sulfate conducts electricity or not is to be determined.
Concept introduction:
An electrolyte is a substance that conducts electricity when it is dissolved in water. The flow of charged particle is the reason behind the conductivity of a solution. The charged particle moves towards the electrode with the opposite charge and conducts electricity.
Ionic compounds and electrolytes such as acid or base behave as electrolytes and conduct electricity.
(b)

What would happen if the carboxylic acid and alcohol groups were on the same molecule? In
essence, the molecule reacts with itself. Draw the structure of the products formed in this manner
using the reactants below. If two functional groups interact with one another on the same molecule,
this is called an “intramolecular" (within one) rather than "intermolecular" (between two or more)
attack.
