What are the factors which affect which affect the conductivity of an electolyte solution? How will you explain weak and a strong electrolyte based on their conductivity values?
The resistance of a 0.5 M solution of an electrolyte enclosed between two platinum electrodes 1.5 cm apart and having an area of 2*0cm^(3) was found to be 30 ohm. Calculate the molar conductivity of the electrolyte.
A graph was plotted between molar conductivity of various electrolytes (NaCl, HCl and NH_4OH ) and sqrtC (in mol L^(-1) ) . Correct set is :
When a certain conductance cell was filled 0.1 mol L^-1 KCl, it has a resitance of 85 ohm and 25^@C . When the same cell was filled with an aqueous solution of 0.052 mol L^-1 of an electrolyte solution, the resistance was 96ohm . Calculate the molar conductivity of the electrolyte at this concentration. (conductivity of 0.1 mol L^-1 KCl solution is 1.29xx10^-2 S cm^-1 )
What is the effect of decreasing concentration on the molar conductivity of weak electrolyte?
Kohlrausch law can be used to find the molar conductivity of a weak electrolyte at infinite dilution.
Molar conductivity of a solution of an electrolyte AB_3 is 150 Scm^2mol^(-1) . If it ionises as AB_(3)toA^(3+)+3B^(-) , its equivalent conductivity will be :
