Questions & Step-by-Step Solutions

Which of the following is a strong base?
Correct Answer: NaOH
  • Step 1: Understand what a strong base is. A strong base is a substance that completely dissociates in water to produce hydroxide ions (OH-).
  • Step 2: Look at the options given in the question. Identify which one is sodium hydroxide (NaOH).
  • Step 3: Know that when NaOH is added to water, it breaks down completely into sodium ions (Na+) and hydroxide ions (OH-).
  • Step 4: Conclude that since NaOH produces hydroxide ions completely, it is classified as a strong base.
