When co2 dissolves in water, part of the co2 reacts with water forming carbonic acid, h2co3, a diprotic acid with the following dissociation constants: ka1= 4.3×10−7 , ka2= 4.8×10−11. consider an aqueous solution containing 0.45 m carbonic acid. calculate the equilibrium concentration of co32− ions in the solution. calculate the equilibrium concentration of hco3− ions in the solution. calculate the equilibrium concentration of h3o+ ions in the solution. enter each of your answer to two significant figures. enter each of your answer in scientific notion. you can use the letter "e" to represent the exponent (for example, 1.0x10−3 should be entered as 1.0e-3).

You mix the pks of succinic acid are 4.21 and 5.64. how many gramsa graduate student at sdsu wants to measure the activity of a particular enzyme at ph 4.0. to buffer her reaction, she will use a buffer system based on one of the acids listed below, which acid is most appropriate for the experiment? of monosodium succinate (fw = 140 g/mol) and disodium succinate (fw = 162 g/mol) must be added to 1 l of water to produce a solution with a ph 5.28 and a total solute concentration of 100 mm? (assume the total volume remains 1 liter, answer in grams monosodium succinate, grams disodium succinate, respectively.) volumes of 0.05 m nah2po4 and 0.05 m na2hpo4 (pk's for phosphoric acid are 2.15, 6.82 and 12.38). which of the following best describes the resulting solution?
