Two copper plates, A (impure) and B (pure) is connected by the battery and inserted into copper sulphate solution. For doing the purification of Impure Copper.
a) Plate A will be connected to negative terminal
b) Plate A will be connected to positive termina
c) Plate A can be connected with either positive or negative terminal
Answers
Answer:
it's A
Explanation:
In the copper purification process, the
pure copper plate is to be coated with
copper from the impure copper plate, so
the pure copper plate is the cathode.
Therefore, the negative terminal of the
battery should be connected to the pure
copper plate, that is, A and the anode iss
the impure plate of copper, that is, B, from
which the copper has to be coated on the
pure copper plate. Here, the solution can
be a salt solution called copper sulphate
solution which is a metallic salt solution.
During the electroplating process or the
purification process rather, the copper
from the impure plate A is transferred to
the pure copper plate B, through the
electrolytic copper sulphate solution.
Hence, The negative ion P
Answer:
Plate A will be connected to negative terminal
Explanation:
Positively charged particles can be connected negatively charged particles for Ion exchange.
