Give reason why:Colour of the solution changes when iron nail is dipped in copper sulphate solution. |
|
Answer» Iron nails when left dipped in blue copper sulphate solution become brownish in colour and the blue colour of copper sulphate fades away. Fe + CuSO4→ FeSO4 + Cu The above reaction is a type of displacement reaction in which one element displaces another element from its compound and takes its place therein. In the reaction, Fe replaces Cu and form a new compound. |
