  4. HNO3

Questions & Step-by-Step Solutions

Which of the following is a weak acid?
  • Step 1: Understand what a weak acid is. A weak acid is an acid that does not completely dissociate into ions in a solution.
  • Step 2: Look at the options given in the question. Identify the chemical formulas or names of the acids provided.
  • Step 3: Check each option to see if it fully dissociates in water or not. Strong acids fully dissociate, while weak acids do not.
  • Step 4: Identify CH3COOH (acetic acid) as the option that does not fully dissociate in solution.
  • Step 5: Conclude that CH3COOH is the weak acid among the options provided.
