From the solution containing copper (+2) and zinc (+2) ions, copper can be selectively precipita...

From among the set of metals-sodium, zinc, iron, copper and silver, select the following giving equation for reaction. One metal which will not displace copper from copper sulphate solutions.

From among the set of metals-sodium, zinc, iron, copper and silver, select the following giving equation for reaction. One metal which will displace copper from copper sulphate solution.

When a strip of copper is introduced in a solution of zinc sulphate , zinc is precipitated.

4 kg of a metal contains 1/5 copper and rest is zinc. Another 5 kg of metal contains 1/6 copper and rest is zinc. The ratio of copper and zinc into the mixture of these two metals :

4kg of metal contains 1/5 copper and rest is zinc. Another 5 kg of metal contains 1/6 copper and rest is zinc. The ratio of copper and zinc into the mixture of these two metals :

An alloy is to contain copper and zinc in the ratio 9:4. If quantity of copper is 24 kg, the quantity of zinc is -

Assertion (A): The colour of copper sulphate solution changes when a piece of zinc is dropped in it Reason (R): Copper is more reactive than zinc.

The alloy of zinc that does not contain copper in good percentage is
