Q20 / 160 · AP EAMCET 2022 (05 Jul Shift 1) · Chemistry

The gaseous mixture used for welding of metals is

  • A
    $\mathrm{C}_2 \mathrm{H}_4, \mathrm{O}_2$
  • B
    $\mathrm{C}_4 \mathrm{H}_{10}, \mathrm{O}_2$
  • C
    $\mathrm{C}_2 \mathrm{H}_2, \mathrm{~N}_2$
  • Correct answer
    D
    $\mathrm{C}_2 \mathrm{H}_2, \mathrm{O}_2$

Solution

Mixture of acetylene and oxygen is used as a fuel for oxy-welding. As this mixture forms flames hot enough, cutting and welding of metals becomes easier.

Hence, the correct answer is option: 'D'.
