    Calculating CO2 Needed to Reduce pH of NaOH Solution to 12

    Thanks for your input everyone. Is there a way to figure out the amount of CO2 needed more accurately than the just stoichiometrically?

    Calculating CO2 Needed to Reduce pH of NaOH Solution to 12

    Right, so it should be CO2 +H2O--->H2CO3 H2CO3 +2NaOH--->Na2CO3 + 2H2O meaning that for every 2 moles of NaOH only 1 mole of H2CO3 is needed thus only 3.8 moles of CO2 are needed?

    Calculating CO2 Needed to Reduce pH of NaOH Solution to 12

    Thanks Borek, I am a little confused though. Here is what I think you are saying. Since the solution of NaOH is 2.6 molar and I have 3 liters of it that would be 7.8 moles. When the pH of the solution is 12 the [OH-] is 0.01 molar so 3 liters of this would be 0.03 moles. 7.8-0.03=7.77 moles...

    Calculating CO2 Needed to Reduce pH of NaOH Solution to 12

    I am trying to perform the calculation that will tell me how much (mass or moles) carbon dioxide (CO2) I would theoretically need to bubble through a 3 liter solution of a 2.6 M aqueous sodium hydroxide (NaOH) solution in order to reduce the pH of the solution to 12. I know that the reaction...
