Please explain in detail what is levelling effect and what i s levelling solvent Also do we have to learn the relative strength of different acids o auto n Any substance such as water which may function as an acid as well a base is called amphoteric Strength of all strong acids HCI H SO HNO HCIO etc in water is same and become equal to the strength of H O ion This is called levelling effect of water So strength of strong acids is compared in glacial acetic acid Water is called levelling solvent and glacial acetic acid is called differentiating solvent for strong acids Levelling effect of water is due to its high dielectric constant and strong tendency to accept protons Strength of all strong bases in water is the same and becomes equal to the strength of OH ion because of levelling effect of water Any acid having acid constant K greater than 1 may be regarded as strong acid Relative strength of acids in glacial acetic acid follows the order HCIO HI HBr H SO HCI HNO H O H PO HF CH COOH H CO H S HCN The strongest acid known is HCIO and strongest base known is CSOH
