Which of the following solutions will have the highest electrical conductivity? A) 0.10 M KF B) 0.045 M Al2(SO4)3 C) 0.10 M Nal D) 0.050 M (NH4)2CO3 E) 0.10 M LiBr

Expert Solution

We have to find the solution that has more ion concentration--

A.) Breaks into k+ and F- , ion concentration = 0.10*2 = 0.20M

B.) Breaks into 2Al3+ and 3SO42-, ion concentration = 0.045*5 = 0.225M

C.) Breaks into Na+ and I-, ion concentration = 0.10*2 = 0.20M

D.) Breaks into 2NH4+ and CO32-, ion concentration = 0.050*3 =0.150M

E.) Breaks into Li+ and Br-, ion concentration= 0.10*2 = 0.20M

As B.) Al2(SO4)3 has highest ion concentration so it has highest electrical conductivity.
