Webb6 mars 2024 · pH is an expression of hydrogen ion concentration in water. Specifically, pH is the negative logarithm of hydrogen ion (H +) concentration (mol/L) in an aqueous solution: pH = -log 10 (H +) The term is used to indicate basicity or acidity of a solution on a scale of 0 to 14, with pH 7 being neutral. WebbpH = -log 10 [H +(aq)] We can write above equation for HNO 3 as below. pH = -log 10 [HNO 3(aq)] pH of 0.1 mol dm -3 HNO 3 solution pH = -log 10 [0.1] pH = 1 You can see, 0.1 mol dm -3 HNO 3 acid solution is strong acidic solution because pH value is well below seven.
