But the product is bit different in aqueous Nacl because aqueous compounds we dont have only Na and Cl but H and O ions are also present so in this H ion will gathered at cathode rather than Na because of high reactivity of Na ions and at Anode we will obtain OH ions because its reactivity is less than Cl ions.
in Concentrated NACl of electrolysis we obtain H ion at cathode because of high reactivity but at anode we will get Cl ions because on concentration
The ions product which gathered on electrodes depends on three things
1) selective discharge of cat ions
2) selective discharge of an ions
3) Concentration of an ions
The reactivity charge of Cat ions is as follow
K+ ion
Na+ ion
Ca+ ion
Mg+ ion
Zn+ ion
Fe+ ion
Pb+ ion
H+
The reactivity of an ion is as follow
So4
NO3
Cl
Br
I
OH
