Find CO 3 ^ 2- ] of 0.080 M M carbonic acid solution You may want...
You create a 1 L solution of 0.1 M H2CO3. carbonic acid, H2CO3, is a diprotic acid with Ka1 = 4.5 x 10-7 and Ka2 = 4.7 x 10-11. a) What will the initial pH of the solution be? b) What volume of 0.1 M NaOH will you need to add to reach the second equivalence point( remember carbonic acid deprotonates to bicarbonate HCO3- and then can deprotonate further to CO32-? c) At the second equivalence point, what will the...
a) Find the concentration of H+, HCO3- and CO32-, in a 0.01M solution of carbonic acid if the pH of this is 4.18. Ka1 (H2CO3) =4.45 x 10–7 and Ka2 =4.69 x 10–11 (b) Calculate the pH at the equivalence point of the titration between 0.1M CH3COOH (25 ml) with 0.05 M NaOH. Ka (CH3COOH) = 1.8 x 10–5.

A) Calculate the concentration of HCO3- in an aqueous solution of 2.68×10-2 M carbonic acid, H2CO3 (aq). [HCO3-] = ___ M. B) Calculate the concentration of C6H6O62- in an aqueous solution of 0.0818 M ascorbic acid, H2C6H6O6 (aq). [C6H6O62-] = ___ M.
A chemist titrates 90.0 mL of a 0.5705 M carbonic acid (H,CO,) solution with 0.6274 M KOH solution at 25 °C. Calculate the pH at equivalence. The pk of carbonic acid is 3.60. Round your answer to 2 decimal places. Note for advanced students: you may assume the total volume of the solution equals the initial volume plus the volume of KOH solution added. DH-
