What is the pH of rainwater in pristine environments? Assume the temperature is 25°C, the total pressure is 1 atm and the rainwater is in equilibrium with the atmosphere. Solution: 5 species are present in the aqueous phase H2CO3(aq), HCO3-(aq), CO3-2(aq), H+ and OH- Equations: 1H2CO3 → H+ + HCO3- (carbonic acid dissociation) K1 = [H+][HCO3-]/[H2CO3] = 4.47 x 10-7M

If you mix equal concentrations of reactants and products, will the reaction proceed to the right or the left? HF (aq) + NO3- (aq) - HNO3(aq) +F- (aq) Match the items in the left column to the appropriate blanks in the sentences on the right Reset Help base .and is a stronger acid than Because proton transfer occurs from the stronger the reaction proceeds to the is a stronger base than to the stronger HNO, acid left right HF NO
