Question

Give one method for industrial preparationand one laboratory preparation of co and co2 each

Answer 1

1. For Carbon monoxide, CO

i. Industrial method:

2C(s) + O₂(g) → 2CO(g)

ii. Laboratory method:

HCOOH + CO → H₂O; Conditions: H₂SO₄, 373 K

2. For Carbon dioxide, CO₂

i. Industrial method:

C(s, excess) + O₂(g) → CO₂(g)

ii. Laboratory method:

CaCO₃(s) + 2HCl(l) → CaCl₂(aq) + CO₂(a) + H₂O(l)
