First post but I thought this might help someone.
Calculation to add CO2 to any room via Sodium Bicarbonate (Baking Soda) and Acetic Acid (Vinegar).
As example I'll assume 10 x 10 foot room with 8 foot ceilings, if different just plug your numbers in.
First, calculate the volume of the room in liters
(average length x average depth x average height) = cubic feet
Then multiply by 28 to get liters.
Eg: 10' x 10' x 8' x 28 = 22,400 liters of air.
Second, calculate needed CO2 to saturate.
To ensure you don't over do it, I recommend adding only an additional 1000ppm or 1%
Multiply total volume by 1% to get needed additional CO2 in liters
EG: 22,400 liters air x 1% = 224 liters CO2
Third, convert to moles of CO2
Divide liters by 22.4 for all ideal gasses
EG: 22.4 / 22.4 = 10 moles CO2
Forth, calculate needed baking soda and acetic acid
1mole acetic acid + 1mole sodium bicarbonate = 1mole CO2 + 1mole Sodium Acetate (thick white stuff on bottom)
Add one mole acetic acid and 1 mole baking soda for every mole need of CO2. (Again don't forget the vinegar is only 5% solution).
EG: 1 mole CO2 would require 1 mole acetic acid and 1 mole baking soda.
Fifth, convert to grams baking soda and ml vinegar
Baking soda has a molecular weight of 84 and Acetic Acid has a molecular weight of 60. therefore just multiple moles needed by molecular weight to get grams.
EG: 10 mole baking soda x 84 = 840 grams Baking Soda
10 mole Acetic Acid x 60 = 600 ml ( as density is about 1g/ml) Acedic Acid
Note: it takes 20 times the volume of vinegar as its only 5% solution
Final = 840 grams Baking Soda and 12000ml (60ml / 5% solution) vinegar will produce 1000ppm CO2 in a "CLOSED" 10 by 10 by 8 foot room.
Other Misc Data:
1 gram baking soda = 1.4ml baking soda
15 ml = 1 Tablespoon Baking Soda
1 Tablespoon baking soda = 10.7 grams
1 cup vinegar = 237 ml vinegar = 11.85 grams acedic acid
Don't exaust air as it will remove CO2, but you should have circulating fan on to keep the CO2 from collecting on the floor.
Another interesting note is a "heavy breath", those you take when exercising strenuously, has .2 liters of CO2 or .007 moles. At 40 breaths / minute during exercise we can produce .28 moles CO2 or 8 liters in 1 minute!
Hope it helps someone.
