    Soda Pop Fizz
    Hi,
    I am trying to complete my science project and I am doing it on the Soda Pop and its fizz.

    I used Powder Citric Acid, C6H8O7, and Baking Soda, NaHCO3, what is the resulting chemical reaction on this?

    Is it C6H8O7 + NaHCO3 -> C6H9O8Na + CO2

    I normally used 1 to 1 ratio but is it better if I use 2 Citric Acid to 1 Baking Soda?

    Thanks for your time in advance.

    1:1 should be fine, as citric acid has 3 equivalents of acid per molecule, but has about 2-1/2 times the molecular weight, so that is about right.

    There is a little more info at this site.
