WebNov 15, 2024 · H2O ⇆ H+ and OH– 2H2O ⇆ OH– and H3O+. pH indicates whether water is proton saturated or acidic or an electron donor or energy donor or alkaline. More H+ = more protons or acids. Less H+ = more electrons or more alkalinity. Because H+ immediately associates with H2O to form H3O+ (Hydronium), pH can also be said to be a … WebpH = -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.
