• Sulfate, SO₄^2–

  Choose...Violet or red-brown vapors of elemental iodine form colorless, odorless gas (carbon dioxide) evolves Colorless, pungent gas, HCl evolves, which turns blue litmus redNo observable reaction

Answer 1

Here I am presenting the behaviour of different acid radicals towards sulphuric acid:

Chloride, Cl^– Colorless, pungent gas, HCl evolves, which turns blue litmus into red.

Here White pungent hydrogen chloride gas will evolve which will make blue litmus into red.

Carbonate,CO₃^2– form colorless, odorless gas (carbon dioxide) evolves.

Effervesence of colorless gas which is Carbon-di-oxide.

Sulfate, SO₄^2– No observable reaction
