Question

a student was given mixture of iron filling and sulphur on heating it we observe the following 1)what is the colour of mixture 2) what is the magnetic effect on mixture III) reaction between CS2 of mixture IV) on adding dilute H2 S o4 what will happen. 5) the name the gas obtained and also write its. properties.

Answer 1

Hey dear,

● Answers -
a) Colour of mixture => Greyish black

b) Magnetic effect on mixture => Nothing

c) No reaction with carbon disulphide.

d) Ferrous sulphate is formed with release of hydrogen sulphide.

e) Gas obtained => Hydrogen sulphide
Properties of H2S => colourless gas with rotten eggs smell.

● Reactions -
Iron fillings react with sulphur to form iron sulphide.
Fe + S ---> FeS

Iron sulphide reacts with sulphuric acid & releases hydrogen sulphide gas.
FeS + H2SO4 ---> FeSO4 + H2S






Hope this helps you...
