Questions & Step-by-Step Solutions

Which of the following is the most acidic among the following oxides? (2019)
  • Step 1: Understand what acidic oxides are. Acidic oxides are oxides that can react with water to form acids.
  • Step 2: Look at the given oxide options. In this case, we are considering P2O5 (phosphorus pentoxide).
  • Step 3: Know that when P2O5 is mixed with water, it reacts to form phosphoric acid (H3PO4).
  • Step 4: Compare P2O5 with other oxides (if provided) to see if they also form acids when mixed with water.
  • Step 5: Determine that since P2O5 forms a strong acid (phosphoric acid), it is the most acidic among the options.
