Answer;

Oxygen

Explanation;

  • A bunsen burner attains a blue gas flame when there is enough oxygen for complete combustion.
  • When there is sufficient oxygen, the gas flame appears blue because complete combustion creates enough energy to excite and ionize the gas molecules in the flame.
  • In other words; increasing oxygen supply, less black body-radiating soot is produced as a result of a more complete combustion and the reaction creates enough energy to excite and ionize gas molecules in the flame, and a blue flame is formed.
