| Feb 16, 2015 at 20:15 | comment | added | VinegrMan | I understand that, "pKa = -log10Ka The lower the pKa value, the stronger the acid." I am not a chemistry student and I have not done these kinds of calculations. I am searching for a convenient way for farmers in developing countries to quickly approximate the strength of vinegar. The final test would be done in a lab but I need a way for them to test vinegar other than titration because titration can seem more like witchcraft than science to the uninitiated :-). | |
