The ph of a solution is correctly defined as

WebbThe pH of a solution is a measure of hydrogen ion concentration, which in turn is a measure of its acidity. Pure water dissociates slightly into equal concentrations of hydrogen and hydroxyl (OH−) ions. (4.12) An excess of hydrogen ions makes a solution acidic, whereas a dearth of H+ ions, or an excess of hydroxyl ions, makes it basic. Webb13 juli 2024 · pH is defined as the concentration of Hydrogen ions Answer: A is correct statement because pH + pOH is 14. If the pH is 7 means the pOH is also 7 and this means both H and OH ion concentration is same. Second statement is wrong because if solution has 10-5 M/L OH ions then the pOH will be 5.

WebbThe pH of a solution is defined as the negative logarithm to the base 10, of the concentration of H + ions in solution in mol dm –3. pH is expressed mathematically as pH = -log 10 [H +] or pH = -log 10 [H 3 O +] Concept: The pH Scale Is there an error in this question or solution? Chapter 8: Ionic Equilibrium - Evaluation [Page 31] Q 13. Q 12. Webb27 okt. 2024 · In simplest terms, a pH value indicates how acidic or basic water is. A pH of 7 indicates a neutral solution, a pH greater than 7 indicates a basic solution, and a pH of less than 7 indicates an acidic solution. The farther a pH value is from 7, the more strongly acidic or basic it is. For example, water with a pH of 6 is mildly acidic, and ...

WebbpH = -log [H + ] Therefore, a H + concentration of 10 - 7 M has a pH of 7.0. In pure water, there are always equal numbers of H + and OH - , and the pH is defined to be neutral.
