Problem 65P
Classify the following substances as strong electrolytes, weak electrolytes, or nonelectrolytes:
(a) Sodium permanganate (NaMnO4)
(b) Acetic acid (CH3COOH)
(c) Methanol (CH3OH)
(d) (d) Calcium acetate [Ca(C2H3O2)2]
ANSWER:
Solution 65P:
Here, we are going to determine the substances as strong electrolytes, weak electrolytes, or nonelectrolytes based on their dissociation property.
Step 1:
A strong electrolyte : It is defined as a substance that completely, ionizes or dissociates in a solution. These ions are good conductors of electric current in the solution.
For example: NaCl is strong electrolyte which dissociates completely in solution.
A weak electrolyte : It is defined as a substance that partially ionizes or dissociates in a solution.
A Nonelectrolyte : It is defined as a substance that does not ionize or dissociate in solution.
For example sugar, fats.
