I have a suspension of bacteria producing Lactic Acid in a saline (NaCl) 2% solution.
I want to calculate the Ph of the solution, considering that the concentration of Lactic Acid reach 0.04M.
Which approach should I take in this case?
In one hand Na+ and CL- are neutral ions and they don't influence the Ph, in another hand, the water on it is not pure H2O.
Does the NaCl concentration in the solution influences the deprotonation of Lactic Acid to Lactate?
In case it does, how do I calculate the Ph of it?
