WebMar 2, 2024 · The range goes from 0 to 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water. Water that has more free hydrogen ions is acidic, whereas water that has more free hydroxyl ions is basic. Webof pH 1 would have ten times (not twice) the [H+] that a solution of pH 2. Likewise, a solution of pH 12 would be 10 times more alkaline than a solution of pH 11. pH Calculations Involving HCl Solutions 1. Given the Wt% of an HCl solution, what is its theoretical pH value?
