Question
What is the change observed when an aluminum strip is kept immersed in freshly prepared ferrous sulphate solution taken in a test tube. Choose one of the following
- Green solution slowly turns brown.
- Test tube's lower end becomes slightly warm.
- A colourless gas is observed with the smell of burning sulphur.
- Light green solution changes to blue.
Hint:
Light green solution changes to blue
The correct answer is: Light green solution changes to blue.
When an aluminium strip is kept immersed in freshly prepared ferrous sulphate solution taken in a test tube, the change which is observed in light green solution changes to blue. In reactivity series, Aluminium is considered to be more reactive as compared to iron i.e., ferrous or ferric.
