You have 3 metals and salt solutions of these metals. Test tube Solution
A student took four test tubes containing solutions of different colours marked I (colourless) II(Blue), III (Orange) and IV (Pale green) . Which of the tubes contain copper sulphate solution and ferrous sulphate solution?
On the basis of the reactivity series of metals, predict how these metals will react with each of the following salt solutions:
Metals: magnesium, zinc, copper, iron, and potassium
Salt solutions: magnesium sulphate, zinc sulphate, copper sulphate, iron sulphate,and potassium sulphate
A student added a few pieces of aluminium metal to two test tubes A and B containing an aqueous solution of iron sulphate and copper sulphate. In the second part of her experiment, she added iron metal to another test lube C and D containing an aqueous solution of aluminium sulphate and copper sulphate. In which test tube or test tubes will she observe colour change? Based on this experiment state which one is the most reactive metal and why?
