A yellow coloured powdery substance A is insoluble in water but soluble in carbon disulphide.It gives a gas when it is heated in presence of air.
IWhat will be the action of this gas on:-
i)dry litmus paper
ii)moist litmus paper
Identify A and write the balanced equations.
1 Answer
Most likely it is Sulfur
The Properties of sulfur are:
Sulfur is not water soluble but is soluble in carbon disulphide.
Sulfur is a yellow powdery substance.
Sulfur will in the presence of oxygen and heat form sulfur dioxide which is a colorless gas.
The reaction is as thus:
S + O2----------> SO2
The dry litmus will not react.
The wet will react as an acid due to this reaction:
SO2 + H2O -----------> H2SO3
