MCQ
What makes a substance a weak electrolyte?
  • A
    It completely dissociates in water.
  • B
    It partially dissociates in water.
  • C
    It does not dissociate in water.
  • D
    It is insoluble in water.

Answer

B. It partially dissociates in water.
Explanation: Weak electrolytes partially dissociate into ions in solution, which means they produce fewer ions and therefore conduct electricity less efficiently compared to strong electrolytes.
