Question

you are provided with container made up of aluminium . you are also provided with the solutions of dil HCl, dil HNO3, ZnCl2, AgNO3 and water out of this solutions which solution can be kept in aluminium container

Answer 1

we can put water and agno3 solution

Answer 2

The container made up of copper or aluminium is suitable for storing some solutions. This can be decided by studying their reactions with Cu and A1 (which also depend on the respective position in activity series).(i) Reactions of copper with(a)Dil. HClCu + HCl ----> No reactionSo, it can be stored in Cu container.(b)Dil. HNO3Being a strong oxidising agent, dil. HNO3 reacts with copper, so it cannot be stored in copper container.©ZnCl2Copper is less reactive than zinc, so it does not react with ZnCl2 solution. Therefore, it can be stored in copper container.(d)H2OCopper does not react with water. So, its container can be used to store H2O.(ii) Reactions of aluminium with(a)Dil. HClAl reacts with dil. HCl, so it cannot be kept in aluminium container.(b)Dil. HNO3When dil. HNO3 is kept in Al container, it forms a protective layer of aluminium oxide on it, therefore it can be kept in Al container.©ZnCl2Al is more reactive than zinc, so it cannot keep ZnCl2 solution in it.(d)H2OAluminium does not react with water (hot or cold). Therefore, water can be kept in aluminium container. Aluminium is attacked by steam to form, aluminium oxide and hydrogen.
