Which of the following solution of KCl will have the highest value of molar conductivity?
Molar conductivity serves as a gauge for the electro-conductive prowess of an electrolytic solution. It quantifies the conductivity within a 1-molar solution of the electrolyte, measured in siemens per meter (S/m).
The molar conductivity of an electrolyte solution rests upon various factors, encompassing solution concentration, temperature, and ion mobility. Typically, as concentration rises, the molar conductivity diminishes, attributed to ion overcrowding impeding their free movement.
In the instance of KCl solutions, molar conductivity dwindles from 149 S/m in infinite dilution to 129 S/m at a concentration of 1 M. This decline is rooted in interionic interactions among K+ and Cl- ions within the solution.
Which of the ensuing KCl solutions will wield the zenith of molar conductivity?
The 0.001 M KCl solution will command the summit of molar conductivity.
Explication:
As previously elucidated, escalating concentration triggers a dip in molar conductivity. Ergo, the solution with the most modest concentration garners the loftiest molar conductivity. In this scenario, the 0.001 M KCl solution, sporting the lowest concentration, emerges triumphant in the molar conductivity hierarchy.
