Dear abhishek,

According to this theory “If more than one type of ion is attracted towards a particular electrode, then the ion is discharged one which requires least energy or ions with lower discharge potential or which occur low in the electrochemical series".

If more than one type of ions are attracted towards a particular electrode , then the one discharged is the ion which requires the least energy . The potential at which the ion is discharged or deposited at the appropriate electrode is termed as the discharged or deposition potential and this discharge potential varies from ion to ion

It states that if more than one type of ions are attracted to a particular electrode, then the ion which is discharged, is the ion which requires the least energy.

When more than one cation and anion are present in solution then which ion will first discharge is given by this theory
