WebJun 4, 2024 · Step 1: Convert pH to [H+] pH is defined as -log [H+], where [H+] is the concentration of protons in solution in moles per liter, i.e., its molarity. If, for example, you have a 0.1 M solution of formic acid with a pH of 2.5, you can substitute this value into the pH equation: 2.5 = -log [H+] WebMar 2, 2024 · pH is a measure of how acidic/basic water is. 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.
WebJan 19, 2024 · Phenolphthalein is colorless under acidic, neutral, and slightly basic conditions. It’s pink between pH values of 8.3 and 10.0 and then becomes colorless again at pH values greater than 10. At extremely low pH, like concentrated sulfuric acid, the color turns orange-red. However, the orange-red color is not seen with all strong acids. WebIf the pH is smaller than 7.00, the solution is an acidic solution; if the pH is larger than 7.00, the solution is an alkaline solution (remembering that this is strictly accurate only at 25°C). Correspondingly, acidic solutions are described by pOH values larger than 7.00 and alkaline solutions by pOH values smaller than 7.00.
