The formula is simple: pH = – log [H3O +] It’s easier to calculate in strong acids because the ions completely dissociate in water. For instance, hydrochloric acid is a strong acid that’s 100% ionised into cations and anions when dissolved in water.

Definition of pH (video) Khan Academy

WebThe pH scale measures the concentration of hydrogen ions in a solution. The following equation gives the pH: pH = - log ( [ H +]) A pH below 7 is acidic, whilst a pH above 7 is alkaline. A neutral solution has equal concentrations of hydrogen and hydroxide ions. Strong acids and bases dissociate completely in solution. WebIf you want an accurate measurement you will typically use a device called a pH meter§. There are also chemicals called pH indicators that can be used. These chemicals are often bound onto small strips called pH paper than change color to give you an estimate of the pH. philips usg
