how the slope of the graph between molar conductivity and square root of concentration has been found.ncert example 3.6 pg 80.explain
The Debye Huckel Onsager equation is
When a graph between molar conductivity Λm verses √C the slope of the graph is obtained as K. Its a negative slope. Slope = tan Ɵ = dy /dx.
When we plot a graph between Λm and √C we observe a small increase in the molar conductivity of strong electrolytes with dilution. This is due to the reason that with dilution interionic interactions decreases. Similarly when we plot a graph between Λm and √C for weak electrolytes , we observe that with dilution the molar conductivity of weak electrolytes increases steeply when concentration approaches zero and becomes parallel to molar conductivity axis.
