Questions & Step-by-Step Solutions

Which of the following is the most acidic oxide? (2022)
  • Step 1: Understand what an acidic oxide is. An acidic oxide is a compound that can react with water to form an acid.
  • Step 2: Look at the options provided. Identify the oxides listed in the question.
  • Step 3: Recall that phosphorus pentoxide (P2O5) is known to react with water to form phosphoric acid (H3PO4).
  • Step 4: Compare P2O5 with other oxides. Determine if they also form acids when reacting with water.
  • Step 5: Conclude that P2O5 is the most acidic oxide because it forms a strong acid compared to the others.
