Question

Based on class 10th Electricity
Why if a pure water is insulator then impure water conducts electricity. What is the difference in their resistance. And why that difference is?​

Answer 1

Answer:

Pure water is neutral so it does not contain any ions in it since pure water does not contain any ions it does not conduct electricity as we know that for the conduction of electricity the presence of ions are must so ions helps in the conduction of electricity.Thus, pure water does not conduct electricity so it is not electrolyte and hence it it offers more resistance.

On the other hand,Impure water maybe acidic or basic since impure water is acidic or basic it contains acidic ions or basic ions that is. H + ions or OH- ions these ions help in the conduction of electricity .Thus, we can conclude that impure water offers less resistance.

There is a difference in the resistance of impure water and pure water this difference is because of the fact that in impure water there are free electrons present in it but in pure water there are no free electrons so it does not conduct electricity.
