- Distinguish between a strong acid and a weak acid in terms of their dissociation reactions and equilibrium constants.arrow_forwardThe scale used for measuring the acidity or basicity of a solution is known as the pH scale. Typically you will see values ranging from 0 to 14, however it is possible to produce highly acidic solutions with a lower pH or a highly basic solution with a higher pH. A neutral solution has an equivalent concentration of hydronium and hydroxide ions, which has a pH of 7 at 25 °C. A pH less than 7 indicates that a solution is an acid, and a pH greater than / Indicates that a solution is a base. Click on the image below to explore this simulation, which demonstrates the pH scale. The pH of the solution is related to the H₂O¹ ion concentration by the equation pH = -log H₂O¹] When you click the simulation link, you may be asked whether to run, open, or save the file.

- The acidity of a solution is measured by its pH. If Ht represents the concentration of hydrogen ions (in moles/liter) in the solution, the pH is defined by pH - log Ht| Based on careful measurements and calculations, a chemist examines two solutions and asserts: "The hydrogen ion concentration of Solution A is 65.86% greater than the hydrogen ion concentration of Solution B."
