Pratyush took sulphur powder on a spatula and heated it. He collected the gas evolved by inverting a test tube over it,as shown in the figure below.
$(a)$ What will be the action of the gas on

$(ii)$ moist litmus paper?
$(b)$ Write a balanced chemical equation for the reaction taking place.

$(b)$ Write a balanced chemical equation for the reaction taking place.
(N/A) $(i)$ There will be no action on dry litmus paper.
$(ii)$ Since the gas is sulphur dioxide $(SO_2)$,it turns moist blue litmus paper to red because sulphur dioxide reacts with moisture to form sulphurous acid.
$(b)$ $S_{(s)} + O_{2(g)} \to SO_{2(g)}$
$SO_{2(g)} + H_2O_{(l)} \to H_2SO_{3(aq)}$
