Question

Assertion (A): Acidification of water decreases its conductivity during electrolysis during electrolysis
Reason(R): H+ ions are released which hinder the flow of charges.​

Answer 1

Answer: The acidification of water increases its conductivity during electrolysis. H+ ions are released which increases the flow of charges. Therefore, both the assertion and reason are incorrect.

Explanation:

• Pure water acts as a weak electrolyte as it lacks ions that are responsible for the conduction of electricity.
• When an acid is added to pure water, it releases H+  in the solution. Therefore, the concentration of ions in the solution increases.
• As the number of ions in the solution increases, the conductivity of the water also increases.
• H+ ions do not hinder the flow of charges, instead, the flow of charges increases due to the presence of H+ ions.
• Therefore, acidification of water increases its conductivity during electrolysis and the flow of charges is also increased due to the presence of  ions.
