If a container of pure water is shaken in the air, the water will dissolve atmospheric carbon dioxide until the dissolved gas reaches the solubility of Co2, 1X10-5 M, the acidity constant K1, of the carbonic acid is 4*10t-7. What would be the pH o with Co2? f the water saturated

Carbon dioxide dissolves in water to form carbonic acid, which is primarily dissolved CO2. Dissolved CO2 satisfies the equilibrium equation CO2(gas)<------>CO2(aq) K=0.032 M*atm-1 The acid dissociation constants listed in most standard reference texts for carbonic acid actually apply to dissolved CO2. For a CO2 partial pressure of 3.1×10-4 atm in the atmosphere, what is the pH of water in equilibrium with the atmosphere?

(8 pts) Carbon dioxide in the atmosphere dissolves in water to establish an equilibrium that can increase the acidity of aqueous solutions in the environment. This equilibrium is CO2 (g) ⇌ CO2 (aq), Kh = 3.1 * 10^2 at 25°C. Kh is called the Henry’s law constant, which relates the solubility of the gas CO2 in the aqueous solution, [CO2], to the partial pressure of CO2 over the solution, p(CO2): [CO2] (M) = Kh * p(CO2) (atm) During the preceding...

12. If gas containing 10% carbon dioxide (CO2(g)) is bubbled into a water at pH 6.35, what is the alkalinity of the water in units of mg/L as CaCO3 assuming all the dissolved carbon dioxide forms carbonic acid species? a) 85 mg/L as CaCO3 [correct] b) 100 mg/L as CaCO3 c) 115 mg/L as CaCO3 d) 130 mg/L as CaCO3

1. Solubility in WATER Check solubility of four solutes in water (H2O). For each solute record how many teaspoons dissolved in 1/2 cup of water. NaCl: Start out with 4 small glasses (cups) and add 1/2 cup of water to each. Put 1/2 level teaspoon (tsp) of salt (NaCl) into the first cup and stir. If it dissolves within 1 minute; add another 1/2 tsp of salt and stir. Count the number of 1/2 tsps you are adding. Repeat until...
