Which of the following statements is correct for the manufacture of sulphuric acid by contact process?

Options

  1. AV 2 O 5 is used for catalytic oxidation of S O 2 to S O 3 .
  2. BS O 3 is absorbed in concentrated sulphuric acid.
  3. CS O 3 is directly absorbed in water.
  4. DBoth the statements V 2 O 5 is used for catalytic oxidation of S O 2 to S O 3 and SO 3 is absorbed in concentr

Correct answer

D. Both the statements V 2 O 5 is used for catalytic oxidation of S O 2 to S O 3 and SO 3 is absorbed in concentr

Step-by-step solution

The Contact Process is used in the manufacture of sulphuric acid. The Contact Process: Step 1: Make sulphur dioxide Step 2: Convert sulphur dioxide into sulphur trioxide (The reversible reaction at the heart of the process). Step 3: Convert sulphur trioxide into concentrated sulphuric acid.
