The answer choices are:
- a) all the substances conduct electricity.
- b) all the substances are strong electrolytes .
- c) all the substances have high dissociation constants.
- d) all the substances contain an equal amount of ions in solution.
Answer:
- a) all the substances conduct electricity.
Explanation:
All strong acids, weak acids, strong bases, and weak bases dissociate in water in some degree, thus they produce ions. Ions are charged particles. They can move freely in water (aqueous solutions) which means that they conduct electricity.
The compounds that dissociate into ions in aqeuous solution conduct electricity and are called electrolytes. Thus, all the substances listed conduct electricity.
As per the other options:
- b) all the substances are strong electrolytes: is false because there are some weak acids and some weak bases which are weak electrolytes.
- c) all the substances have high dissociation constants: is false because weak bases and weak acids have small dissociation constants.
- d) all the substances contain an equal amount of ions in solution: false because strong acids and bases produce high amount of ions but weak acids and bases produce few ions.
