I'm writing a lab report for my physical chemistry module, I'm investigating the critical micelle concentration of CTAB, part of this was performing conductance measurements of CTAB in water. From the data I've gathered I'm supposed to be able to say what the limiting molar conductivity of CTAB is, whilst I have a value for this I'd really like a value to be able to compare it to. I've had a trawl around the internet but it seems like all the measurements are conducted in a water, EG or water, PEG mix. As a result I'm not comfortable saying they're comparable to the results in deionised water. Can anyone point me in the right direction?
