Question

4. You are provided with a material as follows:
LED-1, conducting wires, copper plate-2, zinc plate-2, dil.
Sulphuric acid solution. Using the above material arrange the
experimental setup in the diagramatic form and write the
estimated results obtained by performing above activity?
​

Answer 1

Answer:

Explanation:

Copper does not react with dilute sulphuric acid. So, no reaction will take place when diluting sulphuric acid is poured onto a copper plate. But when concentrated sulphuric acid is poured onto a copper plate, effervescence is observed.

Copper + Conc. → Copper + Hydrogen
