4. The four metals A, B, C and D, are in turn added to the following solutions one by one. The observations made are tabulated below: Iron(II) Sulphate Copper(II) Sulphate Zinc Sulphate Metal Silver Nitrate A No reaction Displacement Displacement No reaction No reaction No reaction No reaction Displacement D No reaction No reaction No reaction No reaction Answer the following based on the above information: (i) Which is the most reactive metal? Why? (ii) What would be observed. If "B" is added to a solution of Copper (II) Sulphate and why? (iii) Arrange the metals, A, B, C, D in the order of increasing reactivity. (iv) Which one among A, B, C and D metals can be used to make containers that can be used to store any of the above solutions safely?
Science behind corrosion-test
Corrosion is defined as an activity that transforms refined metals into more chemically stable forms such as oxide, hydroxide, carbonate, or sulfide. It refers to the slow decomposition of things (typically metals); thanks to chemical and/or electrochemical reactions with their surroundings. Corrosion engineering is the science of preventing and controlling corrosion.
