WebJan 25, 2014 · We expect the pH of the solution at the equivalence point to be neutral, i.e. pH = 7. Why do we expect that? Well, neither NaX + nor ClX − will react with water in any protolysis reaction. [We do not consider any ionic strength effects on the pH in this reasoning.] Suppose you titrate a weak base with a strong acid: NHX3 + HCl = NHX4X + + … WebMay 6, 2024 · The pH scale usually ranges from 0 to 14. Aqueous solutions at 25°C with a pH less than 7 are acidic, while those with a pH greater than 7 are basic or alkaline. A pH level of 7.0 at 25°C is defined as "neutral" because the concentration of H 3 O + equals the concentration of OH − in pure water.

WebThe pH scale is a convenient way to represent the acidity or basicity of a solution. We can calculate the pH of a solution by taking the negative logarithm of the hydronium ion concentration, or pH = -log[H₃O⁺]. At 25°C, a solution with pH < 7 is acidic, a solution with pH > 7 is basic, and a solution with pH = 7 is neutral. Created by Jay. WebJan 28, 2024 · The pH of a neutral solution is 7. A pH of less than 7 indicates that the substance is acidic or alkaline. The pH of pure water is 7 due to the fact that it contains … 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 … fix a clicking hard drive
