please help

this question was witten by Gen Chem Lab Coordinator at Western Washington University (W Explain why the conductivity of 0.126 M Nal(aq) is about twice that of 0.063 M Nal(aq) Since the 0.126 M Nal is twice as concetrated as 0.063 M Nal, each ion is allowed to carry twice as much electrical charge in solution The nature of the ions in solution for 0.126 M Nal are different than those in the 0.063 M Nal and the ions in the 0.126 M Nal carry the charge better. The 0.126 M Nal consists of Na2 and 122 ions in solution whereas the 0.063 M Nal only has Na* and I ions in solution. Nal is a weak electrolyte and ionizes twice as much in the 0.126 M Nal as it does in the 0.063 M Nal There are twice as many ions in solution in 0.126 M Nal than there are in 0.063

Explanation / Answer

Since the 0.126M NaI is twice as concentrated as 0.063M NaI, each ion is allowed to carry twice as much electric charge in solution
