Sodium carbonate (2.4134 g) is dissolved in enough deionized water to give a solution with a total volume of 250.0 mL. What is the pH of the resulting solution? Hint: For carbonic acid, pKa1 = 6.351 and pKa2 = 10.329. What is the equilibrium concentration of H2CO3 in the solution? calculate the value of alpha HCO3-. I already have the answer to the first part of the question. I just need the equilibrium concentration and value of alpha please!
