Ph of water saturated with co2

WebDec 25, 2024 · Carbon dioxide does not have a pH, because it is a gas. Explanation: However, an aqueous solution of carbon dioxide has a pH, because the carbon dioxide reacts with the water to form carbonic acid. There is a complex series of equilibria: (1)mCO2(g) ⇌ CO2(aq);kH = 29.76 L⋅atm⋅mol-1 (2)mCO2(aq) ⇌ H2CO3(aq);Kh = 1.7 ×10-3 WebThe hydration equilibrium constant at 25 °C is called K h, which in the case of carbonic acid is [H 2 CO 3 ]/ [CO 2] ≈ 1.7×10 −3 in pure water [14] and ≈ 1.2×10 −3 in seawater.
