A student was asked to carry out a chemical reaction by placing four different metal strips in CuSO₄ solution for a considerable time, one by one. Which of the following metal strip will turn the blue CuSO₄ solution to a colourless solution in due course of time?
(1) Fe (2) Au
(3)Mg (4)Ag
"

Correct answer: (3) Mg

Explanation: As magnesium is most reactive(in the above-given options) so that it will displace the copper (Cu) from its sulphate (CuSO₄) solution and the blue colour will gradually become colourless.

The chemical equation for the above reaction is given below:

$Mg (s) + 2CuSO_4 (aq) → Mg(SO_4)_2 + 2Cu (s)$

A student was asked to test an unknown colourless solution with an indicator. When he added a few drops of phenophthalein indicator, the solution turned pink. Which one of the following chemicals should be added in excess so as to obtain the colourless solution again?(1) HCI solution (2) NaOH solution (3) NH3 solution (4) NaCI solution
A student was given two metal strips X and Y alongwith colourless silver nitrate solution to perform two separate displacement reactions. When the student placed metal strip X in silver nitrate solution for a considerable time, he observed that the solution turned blue and a coating of silver metal was formed on the strip. And when the student immersed metal strip Y in silver nitrate solution for an equal time, he observed that the solution turned light green with the formation of a coating of silver metal on the strip. The correct conclusion of the student about the identity of metals X and Y is :(1) X is copper and Y is magnesium(2) X is zinc and Y is copper(3) X is iron and Y is copper (4) X is copper and Y is iron
