Differentiate between the following pair based on the information given in the brackets. Conductor and electrolyte (conducting particles)

A conductor is a substance that has the ability to conduct electric current in the form of electrons, either in molten or in solid state is called as conductor. Copper and iron are the conductors of electricity. An electrolyte is a salt solution that conducts electricity due to the ionisation of salt. The major electricity carriers in an electrolyte are the ions. An acidic solution of copper sulphate and a solution of sodium chloride are some electrolytes.

For the electro-refining of copper, write the reaction that takes place at the anode.

During the electro-refining of copper, the pure copper will be deposited at the cathode and at the anode, the impure copper undergoes oxidation to form Cu 2 + ions. The anodic reaction can be given as, Cu - 2 e - → Cu 2 + .

Name the gas that is produced in the following case: At the anode during the electrolysis of acidified water.

Suppose H + A - acid is dissolved in water. During electrolysis of the acidified water, H + , A - and OH - ions are formed. H + ions migrate to the cathode, while A - and OH - migrate to the anode. Preferentially, OH - ions undergo oxidation to form water and liberate oxygen gas.

State one relevant observation for of the following: At the anode, when molten lead bromide is electrolyzed using graphite electrodes.

During the electrolysis of molten lead bromide, bromine ions migrate to anode. It undergoes oxidation to bromine atom. Two bromine atoms combine to form a gaseous bromine molecule. This gas is observed as a brown fumes at anode. Lead ions migrate to cathode and undergoes reduction.

Name the particles present in Weak electrolyte.

Compounds which in the fused or in the aqueous solution state are feebly or partially dissociated and are poor conductors of electricity are called weak electrolytes. The particles present in weak electrolytes are ions as well as molecules.
