I am a chem student and most of my work has been about lowering Ph levels of H20 using strong acids such as HBr or HClO4 or weak acids such as HNO2 or HF.
I am wondering if the principles apply to using weak acids like citric acid or acetic acid to change the Ph of organic solvents such as alcohols and non-polar solvents.
As an example: If I need x amount of acetic acid to lower the Ph of H20 from 7 to 4, would the same amount of acetic acid be required to lower the Ph of ethanol (let's assume the Ph of ethanol is 7 instead of 7.4) to 4 as well? Or would I need to take other things into account?
Since Ph is a measurement of H+ ions dissociated in solution, what factors are in play when measuring H+ concentration in a solution that is not H20?
