Molar conductivity is just conductivity per mole, so you are taking moles to be constant i.e 1 mol and volume to be variable here Whereas specific conductivity is conductivity per unit volume, so you are taking volume to be constant i.e 1m^3 and number of moles to be variable So on increasing concentration: Only number of moles increases for specific conductivity Only volume decreases for molar conductivity(moles of ions remain same) As a result: Conductivity increases for specific conductivity Conductivity decreases for molar conductivity
6:32 sir why are we not stating that volume v must be 1 lit? bcz molar conductivity is conductivity per unit conc. and unit conc. means 1 mol/lit but the conc we have taken is 1/v know sir?
I don’t think he will answer you so i will answer, unit concentration means 1mol/liter yes correct but it turns into a value basically, concentration doesn’t need to be only in one liter, its just a value that you take 1 liter for calculating but concentration itself is not only one liter, it’s basically just a number. Now for calculating molar conductivity its basically conductivity/concentration (just the value number you found, not necessarily one liter) so it’s not compulsory that it needs to be one liter, tell me if still not clear..
still, ia m not comfortable with the molar conductivity

excellent explanation, cleared lots of my doubts from the class
wonderful explanantion ! this is called science
perfection🤩🤩
THIS IS WHAT I NEED... THANK YOU
FINALLY understood it :) thank you so much
Very nice explanation, kudos!
Lovely explanation. Absolutely crystal clear 🙌🏻
Thank you sir❤ from Sri Lanka 🇱🇰❤
