Ph of water saturated with co2
WebSep 13, 2024 · Because dissolved carbon dioxide is acidic, rainwater that is saturated with this gas is naturally acidic—usually about pH 5.6. Limestone, calcium silicate, and feldspars in soils and other geological formations dissolve through the action of carbon dioxide to increase the concentration of bicarbonate in water and raise the pH. WebThe CO2 is an acidic oxide, reacting with H2O to form H2CO3. What is the pH at 25 ∘C of water saturated with CO2 at a partial pressure of 1.20 atm ? The Henry's law constant for …
