Summary for percent of acid in tank Discussion
percent of acid in tank is the core question here: Jason Krause asked whether a hydrometer is the right way to check sulfuric acid concentration in an anodizing tank held at 25 to 30 °F, and whether wet-lab testing means acid titration. The only answer in the thread comes from James Watts, who does not walk through the chemistry or formula, but instead strongly recommends getting a copy of the Metal Finishing Guidebook. He says its analysis section covers important facts that the questioner has not asked for and suggests subscribing to the magazine and requesting an immediate copy of the guidebook. Watts also notes that Ted or Tom used to sell back issues for enough to cover shipping and handling, and that the analysis section has not changed in years. The thread therefore points readers toward a standard reference rather than a step-by-step titration procedure.
Q. We are using a hydrometer to test the percent of acid in our anodizing tank and I was told this is not the best way to make this check. We are using sulfuric acid and water at 25 to 30 °F. I was told wet lab testing is the best way to make this check, is this acid titration? if so how do I find the percent with this method? I understand the procedure but I am not clear with chemistry and the formula so laymen’s terms will help me a lot

A. I would strongly recommend that you get a copy of the
Metal Finishing Guidebook. It has an excellent analysis section and will include several facts that are pertinent that you have not asked for. I would sign up for the magazine and ask for an immediate copy of the guidebook. Ted or Tom used to sell some back issues that they had for enough to handle shipping and handling. The analysis section has not changed in years.
