Physico-chemical exploration of solution behaviour of some metal perchlorates prevailing in N-methyl formamide with the manifestation of ion solvent consequences

•LiClO4 is more associated in N-methyl formamide than the other two perchlorates.•Ion–solvent interaction predominates over the ion–ion interaction in all the studied solutions.•Lowest ion–solvent interaction is seen in KClO4.

Electrical conductance of lithium perchlorate, sodium perchlorate, potassium perchlorate in pure N-methyl formamide have been measured at 298.15 K. Limiting molar conductance (Λo), association constants (KA) and co-sphere diameter (R  ) for ion-pair formation have been examined by using Fuoss conductance equation. Viscosity B-coefficient, apparent molar volume (ϕVϕV) and apparent molar adiabatic compressibility (ϕKϕK) have been achieved from viscosity (ηη), density (ρρ) and speed of sound (c  ) measurements respectively. The limiting apparent molar volume (ϕV0) and experimental slope (SV*) have been interpreted in terms of ion–solvent and ion–ion interactions respectively. The viscosity data have been analysed using Jones–Dole equation and derived parameters A and B represent ion–ion and ion–solvent interactions respectively. The c   values have been used to determine adiabatic compressibility (βSβS) and limiting apparent molar adiabatic compressibility (ϕK0).
