Question

Which one of the following solutions will have highest conductivity? (A)  0.1 M CH3COOH  (B)  0.1 M NaCl  (C)  0.1 M KNO3  (D)  0.1 M HCl

Tardigrade Admin · Accepted Answer

NaCl , KNO 3, HCl are strong electrolytes but the size of H +is smallest. Smaller the size of the ions, greater is the conductance and hence greater is the conductivity (k=C × cell const. )

Q. Which one of the following solutions will have highest conductivity?

$0.1 M C H_{3} COO H$

$0.1 M N a Cl$

$0.1 M K N O_{3}$

$0.1 M H Cl$

$N a Cl, K N O_{3}, H Cl$ are strong electrolytes but the size of $H^{+}$ is smallest. Smaller the size of the ions, greater is the conductance and hence greater is the conductivity $(k = C \times$ cell const. )
