Question

true and false
1- on adding an impurity to water its electrical conductivity increases.
2- the process of extracting metals from their ores is known as electrorefining.
3- the presence of an electrolyte is not necessary for electrolysis.
4- during electrolysis anions move towards anode.
5- cathode in an electrolytic cell that furnishes free electrons.
6- during electrolysis of table salt solution,chlorine gas is evolved at anode.

Answer 1

1. True.. yes because pure water do not conduct electricity

2. False ...its called metallurgy

3. False

4. True

5. (Not sure abt the answer)

6. True...

Answer 2

Modern electroplating begins with the creation of a metal salt using the plating metal, typically gold or silver. These salts .

Yea the impurities dissolved in water increased its conductivity becouse the impurities contains salt or acid or base which .
