please help me find the cation and anion nominal
concentrations for columns 4 and 5. the original solutions used as
sources of ions are all 0.20 M.
I'd appreciate if you showed the process as well as the
answers.
thank you!
no
equilibrium constant was given. It says the dilution equation must
be used to determine the the nominal concentrations.
