Pratyush took sulphur powder on a spatula and heated it. They collected the gas evolved by inverting a test tube over it, as shown in figure below.
(a) What will be the action of gas on :
(i) dry litmus paper ?
(ii) moist litmus paper ?
(b) Write a balanced chemical equation for the reaction taking place.

Text Solution
