Account for the following : For a strong electrolyte molar conductivity decreases as concentration increases. |
|
Answer» SOLUTION :(i) For a strong electrolyte, at high concentration, the number of constituent ions of the electrolyte in a given volume is high and hence the attractive force between the oppositely charged ions is also high. (ii) Moreover the ions also EXPERIENCE a VISCOUS drag due to greater solvation. (iii) These FACTORS attribute for the low molar conductivity at high concentration. |
