Hydroxyl (OH– ) ion is lower in the activity series, than chloride ion. Yet when a concentrated solution of hydrochloric acid is subjected to electrolysis, the hydroxyl ion does not get discharged.

Hydroxyl (OH– ) ion is lower in the activity series, than chloride i

1.	Hydroxyl (OH– ) ion is lower in the activity series, than chloride ion. Yet when a concentrated solution of hydrochloric acid is subjected to electrolysis, the hydroxyl ion does not get discharged.
Answer» If an electrolyte has a much higher concentration of ions that are higher in the electrochemical series than those that are lower, then the higher gets discharged in preference to the lower one. Concentrated hydrochloric acid being strong electrolyte gets fully dissociated furnishing H⁺ and Cl^– ion. Water is less dissociated into H⁺ and OH^– ion. Thus, concentration of chloride ion is more as compared to OH^– ion and hence, chloride ion are discharged in preference to the OH^– ion
