I know, pH=-log (H+); where H+ is a conc. of H+ or H3O+ given by molarity (M).
To calculate molarity the volume of total system is taken to be 1 L, but for theoretical calculations what is to be considered as a volume of the system where the molecules present are far less than Avogadro's number.
Dear Saeed:
Thank you for your reply. I did try calculating according to the methodology mentioned by you but it didn't give me the answer as expected based on the papers I am reading (unfortunately the reference paper I am looking at doesn't explain the way they calculated the pH, wrote to the author but no response by him/her).
However, I will try doing the calculations again. Also, in your reply what do you thing the "v" needs to be. It can be physical volume of theoretical system (that will include free volume) or total molar volume of the species in the system.
Thank you once again for your kind reply. Your help and feedback is highly appreciated.
Regards
Radhika
