This has got to be one of the worst explanations. No following at all, tried it on a problem 4 different times following the forumla and such and it sucked.
a) In the simulation, select the solutions indicated below from the dropdown list at the top left corner of the simulation. The beaker will fill up to the 1.00 LL mark with the solution. Arrange the acids in increasing order of acidity. Rank from lowest to highest. To rank items as equivalent, overlap them. Beer,vomit,coffee,milk,battery acid,soda pop. b)In the simulation, select the custom liquid from the dropdown list. The beaker will be filled to the 1.00 LL mark with the solution. Set the pHpH to 8.55 by entering the value in the text box provided above the pHpH scale in the panel called "pHpH." Once you adjust the pHpH, note the corresponding OH−OH− ion concentration in mol L−1mol L−1 as given in the graph on the right side of the simulation. Make sure to click the option "Concentration (mol L−1mol L−1)" under the “Water components” panel. Click on the Logarithmic scale below the graph. Find the pOHpOH of the solution.

How do I do the calculation(s) here to determine the information I will need to enter/graph in Excel?! (I can do the graph, mainly need help with the (chem-) math). Using the following information, draw the species diagram for the aqueous carbon dioxide bicarbonate ion-carbonate system at 25 °C: [H2CO3] + [HCO3-] + [CO32- ] = C K1 = [HCO3-] [H+] / [H2CO3] K2 = [CO32-] [H+] / [HCO3-]
