pH = -log 10 [H +] [H +] = 10 -pH. In other words, pH is the negative log of the molar hydrogen ion concentration or the molar hydrogen ion concentration equals 10 to the power of the negative pH value. It's easy to do this calculation on any scientific calculator because more often than not, these have a "log" button. Visa mer There are several ways to define acids and bases, but pH specifically only refers to hydrogen ion concentration and is applied to aqueous(water-based) solutions. When water dissociates, it yields a hydrogen ion and a hydroxide. See … Visa mer The equilibrium equation yields the following formula for pH: In other words, pH is the negative log of the molar hydrogen ion concentration or the molar hydrogen ion … Visa mer When you're performing pH calculations, always make sure your answers make sense.

WebbLogarithmic scale. A logarithmic scale (or log scale) is a way of displaying numerical data over a very wide range of values in a compact way. As opposed to a linear number line in which every unit of distance corresponds to adding by the same amount, on a logarithmic scale, every unit of length corresponds to multiplying the previous value by ... Webb30 jan. 2024 · pH = pKa + log ([conjugate base]/[weak acid]) pH = pka+log ([A-]/[HA]) pH is the sum of the pKa value and the log of the concentration of the conjugate base divided by the concentration of the weak acid.
