A student added few pieces of aluminium metal to two test tubes A and B containing aqueous solutions of iron sulphate and copper sulphate. In the second part of her experiment, she added iron metal to another test tubes C and D containing aqueous solutions of aluminium sulphate and copper sulphate.
In which test tube or test tubes will she observe colour change? On the basis of this experiment., state which one is the most reactive metal and why?
Answers
Answer: A, B and D test tube
Explanation:
When Aluminum metal is added to the A and B test tubes which contains aqueous solutions of iron sulphate and copper sulphate reaction will occur and as the aluminum is very reactive metal so it react with the iron and copper so the color of the solution will be changed in both A and B test tubes.
But when the iron metal added in the C and D aqueous solution of aluminum sulphate and copper sulphate then no reaction will take place in the test tube C but in the D test tube copper will replaced by aluminum.
So the color change will occur in A, B and D test tube. After all experiment we know that aluminum is the most reactive metal as it replaces iron and copper both.
Here is your answer dear....
Answer:
Tube A,B,C
Explanation:
When Aluminum metal is added to the A and B test tubes which contains aqueous solutions of iron sulphate and copper sulphate reaction will occur and as the aluminum is very reactive metal so it react with the iron and copper so the color of the solution will be changed in both A and B test tubes.
