Hi,
I need to conduct experiments at fixed pH. The complication is that the solution I'm using will have NaCl in it. So if I add HCl or NaOH to make the solution more acidic or basic, the conductivity of the solution (as measured by a conductivity meter) will change due to the added Na+ or Cl-.
So I'm wondering if there's a way to control pH without changing the ion concentrations. Would using a pH buffer be a good solution to this?
Thanks,
Urmi
