Chemistry · Ionic equilibrium: Weak and strong electrolytes, ionization of electrolytes

Which one of the following is a strong electrolyte?

Which one of the following is a strong electrolyte?

  • A. \( C H_{3} \) СООН
  • B. \( H C O O H \)
  • C. \( H_{2} C O_{3} \)
  • D. \( N a O H \)

Step-by-step solution

Strong electrolytes completely dissociate into ions in aqueous solution. NaOH (sodium hydroxide) is a strong base that fully dissociates, making it a strong electrolyte. The other options are weak acids (CH3COOH, HCOOH, H2CO3) that only partially ionize, thus they are weak electrolytes.
