I have a HDX (Home Depot) branded 5-way test kit -- the same kit that's manufactured and sold by Poolmaster. I use far more #3 reagent than the others so my #3 bottle is running low yet all the others are still nearly full.
The front side of the label says "#3 - Count Drops - For Acid Demand & Alkalinity Test" and the back says "Contains Hydrochloric Acid ..." but the HCl concentration is not specified.
How can I determine the HCl concentration of this reagent so I can make my own?
