Question

Metal ,,A" is found in earth crust and on exposure to moist air,it forms a reddish brown flaky substance.When a container made up of metal,,A" is used to store a blue coloured solution ,,B", the blue colour changes to pale green and reddish brown metal,,C" is formed.Identify A,B,C and write a balanced equation for the reaction

Answer 1

A - Iron (Fe) is used to store a blue-coloured solution.

B - Copper Sulphate (CuSO4), the blue colour changes to pale green

C - Copper (Cu) reddish brown metal which is formed.

• On the Periodic Table of the Elements, Group 8 of metals includes the brittle, hard material known as iron.
• Its pure form quickly corrodes when exposed to humid air and high temperatures, making it the most plentiful of all metals.
• Iron is estimated to make up a sizable portion of the Earth's core and is the fourth most frequent element in the planet's crust by weight.
• According to the Los Alamos National Laboratory, in addition to being frequently found on Earth, it is also widely distributed in the sun and stars.
• As a result, when iron and copper sulphate mix, iron replaces the copper in the copper sulphate to generate ferrous sulphate. As a result of this displacement, the solution's colour changes from blue to pale green.
