Pratyush took sulphur powders on a spatula and heated it. He collected the gas evolved by invertinv 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

Verified by Experts

(i) there will be no action on dry litmus paper.
(ii) The colour of litmus paper will turn red because sulpher is a non metal and the oxides of non metal are acidic in nature.
b. `S(s)+O_(2)(g)toSO_(2)(g)`
