Question

Copper sulphate solution can be safely kept in a vessel of:
(This question has multiple correct options)
$A.$ Platinum
$B.$ Lead
$C.$ Silver
$D.$ Zinc

Answer 1

Hint: The given question can be solved on the basis of reactivity of these given metal if the reactivity of metal is greater than copper then it is not suitable to store the copper sulphate solution or if it is less reactive so copper sulphate solution can be safely kept in the vessel of that metal.


Complete answer:
We know platinum and silver are less reactive elements; they do not react with other chemicals at ordinary conditions whereas lead and Zinc can react with other chemicals. As we know platinum and silver are less reactive than copper so they cannot displace the copper element from the copper sulphate solution whereas lead and Zinc are more reactive than copper they can displace the copper element from copper sulphate solution. Therefore, we can say copper sulphate solution can be safely kept in a vessel of platinum and silver.

So, the correct options are $A$ and \[C\] .


Additional information: Copper sulphate solution is a chemical compound with the formula $CuS{O_4}$ , the colour of this solution is blue and the older name of this compound blue vitriol and blue stone.


Note: The reactivity of metal can be determined from reactivity series, the reactivity series list metal compounds in their order of reactivity the least reactive metal is placed at the bottom whereas the most reactive metal is placed at the top of reactivity series. According to the reactivity series potassium metal is most reactive among all the metal and platinum is the least reactive metal among all the metal.
