Question

name the substance which remains in a test tube after heating ferrous sulphate. Explain with reason.​

Answer 1

Explanation:

feS04=Fe2O3+SO2+SO3

• ferrous sulpahte ---heated-- ferrous oxide + sulphur dioxide+sulphur trioxide
• it is a thermal decomposition reatction
• when ferrous sulphate is heated its constituents particles remain in the test tube that is ferrous oxide will only remain in it and another two constituent that is S02 and S03 will go and mix with the air so only ferrous oxide will be left
