Measuring concentration of acetic acid and other organic acids in an aqueous solution
If I have an unknown aqueous solution that exhibits a pH of approximately 4.0 but is known to consist of predominantly organic acids such as acetic acid, formic acid, benzoic acid, pyruvic acid, phenolic acid etc. etc.
What analytical method would be employed to measure and determine the concentration of each acid in solution. Would this be a GC/MS analysis
