Carbonic acid (H2CO3) is a diprotic acid (Ka1 = 4.5 x 10-7 and Ka2 = 4.7 x 10-11) and plays a role in blood chemistry, cave formation, and ocean acidification. Calculate the equilibrium values of [H3O+], [HCO3-], [H2CO3], and [CO32-] and find the pH of a 0.075 M H2CO3 solution.

Rainwater is acidic because CO2(g) dissolves in the water, creating carbonic acid, H2CO3 (Ka1=4.3×10−7,Ka2=5.6×10−11). If the rainwater is too acidic, it will react with limestone and seashells (which are principally made of calcium carbonate, CaCO3). Part A Calculate the concentrations of carbonic acid, bicarbonate ion (HCO3−) and carbonate ion (CO32−) that are in a raindrop that has a pH of 5.80, assuming that the sum of all three species in the raindrop is 1.0×10−5M. Express your answers using two significant...

The interaction between carbon dioxide and water results in formation of carbonic acid, H2CO3, which lowers the pH of water through the reactions H2CO3(aq)+H2O(l) <---> HCO3-(aq) + H3O+(aq) Ka1= 4.3*10^-7 HCO3-(aq) +H2O(l) <---> CO3 2- (aq) + H3O+ (aq) Ka2=5.6*10^-11 This dissocociation causes "normal" rainwater to have a pH of approximately 5.7. However, H3O+(aq) can also come from other sources, particularly from acids resulting from interactions of water with industrial pollutants. Scientists studying a particular lake found that its pH...
