(b) name the process associated with the circuit shown here.
(c) name the gases produced at A and B.

Answer 1

Answer:

1. The electrodes can be of platinum or Graphite (as they are inert and non reactive)
2. The process associated here is Electrolysis of Water
3. The gas produced at A (anode(+)positive terminal) is Oxygen(O2) and at which is negative terminal is Hydrogen (H2)

Answer 2

Answer:

1 a- anode

b-cathode

b) electrolysis
