Question

when aqueous solutions of KCl is electrolysed, resultant solution has ph

Answer 1

The answer of you question is “ Basic pH “ or “pH more than7”

When the KCl solution is eletrolysed the it will dissociate in to potassium and chlorine ions

KCl⇒ K+  +  Cl-

The Cl- anion produced will attract the H+ from water while the K+ will not hydrolyzed . The H+ attration by the chlorine will result in OH- ions .

Cl- + H20⇒ HCl+ OH-

The production of OH- will make the solution basic .

Answer 2

Answer:

Explanation:kcl on hydrolysis provides potassium and chloride ions

Since in electrochemical series potassium ion is less reactive than hydrogen ion due to its less electrode potential hence it will not hydrolyse but cl ion will rapidly react with water to give hcl + oh

Due to hydroxide ion kcl shows ph greater than 7
