  4. Urea

Questions & Step-by-Step Solutions

Which of the following compounds is a strong electrolyte?
Correct Answer: Sodium chloride
  • Step 1: Understand what an electrolyte is. An electrolyte is a substance that can conduct electricity when dissolved in water.
  • Step 2: Learn the difference between strong and weak electrolytes. Strong electrolytes dissociate completely into ions in solution, while weak electrolytes do not.
  • Step 3: Identify the compound in question. In this case, we are looking at sodium chloride (NaCl).
  • Step 4: Determine if sodium chloride dissociates in water. When NaCl is added to water, it breaks apart into sodium ions (Na+) and chloride ions (Cl-).
  • Step 5: Conclude that since sodium chloride dissociates completely into ions, it is classified as a strong electrolyte.
