The benzene are sulphonated using acid sufuric.
Please show me how the substitution happened as i really don't see how SO3H can attached to the benzene group and how the SO3H are separated from H2SO4. I really need to understand this substitution..
Thanks

how we determine conductivity of powder??
hmm...i got a question..
i had three inorganic polymer (powder/solid form) and i want to mixed it according to various composition.
how can i determine the conductivity? do i need special equipment to read the conductivity or can i just dissolved...
I have 1 bottle of HCL 37% Concentration with 2.5L Volume. Given the MW is 36.46g/mol. How to calculate the molarity of the HCL in the bottle? as i only need to prepare 1M of HCL?
:confused: no density and molarity given in d label
