Which of the following statements is true for strong electrolytes?

  1. They partially dissociate into ions in solution.
  2. They do not conduct electricity in the molten state.
  3. They completely dissociate into ions in solution. ✓
  4. They are non-polar substances.

Explanation

Strong electrolytes break apart completely into ions when dissolved in water. Every molecule separates into its individual positive and negative ions.

Examples include salts like sodium chloride and strong acids like hydrochloric acid. When these dissolve, 100% of the molecules split into ions.

Complete dissociation allows strong electrolytes to conduct electricity very well in solution. The free-moving ions carry electric current through the liquid effectively.
