Question

Which would you expect to have the greatest conductivity value:

.1 M CsCl

.1 M MgCl2

.01 M SrBr2

.05 M CCl4

Answer 1

0.1 M MgCl2

Greater the number of ions in a particular solution, greater the conductivity.

So; the conductivity depends on number of ions.

Here; CCl4 is not an ionic compound. So; 0.05 M CCl4 doesn't show greater conductivity.

In othersSrBr2 having low concentration of 0.01 M. So; the conductivity of 0.01 M of SrBr2 is less.

Both CsCl and MgCl2 are having same concentration. But MgCl2 produces more ions than CsCl

MgCl2 produces Mg+2 and 2 Cl-

CsCl produces Cs+ and Cl-

So; Number of ionis in MgCl2 are more.

So; 0.1 M MgCl2 have greatest conductivity.
