(choose chapter or problem)

A.K. Srivastava, R.A. Samant, and S.D. Patankar (J. Chem. Eng. Data 41, 431 (1996)) measured the conductance of several salts in a binary solvent mixture of water and a dipolar aprotic solvent 1,3-dioxolan-2-one (ethylene carbonate). They report the following conductances at 25C in a solvent 80 per cent 1,3-dioxolan-2-one by mass: NaI c/(mmol dm3) 32.02 20.28 12.06 8.64 2.85 1.24 0.83 m/(S cm2 mol1) 50.26 51.99 54.01 55.75 57.99 58.44 58.67 KI c/(mmol dm3) 17.68 10.8 87.19 2.67 1.28 0.83 0.19 m /(S cm2 mol1) 42.45 45.91 47.53 51.81 54.09 55.78 57.42 Calculatem for NaI and KI in this solvent and (Na) (K). Compare your results to the analogous quantities in aqueous solution using Table 21.5 in the Data section.
