Please solve both of the questions. Thank You

b. Calculate the equilibrium pH of a 1.23x104 M solution of H2CO3". Assume that [H"]= [HCO3 ] at equilibrium. pKai = 6.35, pKq2 = 10.33. c. Use the figure on the next page to determine the [H2CO3*], [HCO3 ], and [CO3?'] for a solution with a total carbonate species concentration (CI.co3) of 10' M at pH 6.0, 7.0, and 8.0. Submit the below graph along with your homework submission demonstrating that you know how you solve the problem. pH 2 4. 6 8 10 12 -2.0 -2.5 -3.0 -3.5 logo -4.0 -4.5 -5.0 -5.5 -6.0 H2CO3* HCO3- -CO3-2
