# What Ratio Of Vinegar To Baking Soda Produces The Best Chemical Volcano Eruption?

The best ratio I have figured out is 1/4 of a cup of baking soda and 1/2 of a cup of vinegar. This will work in a plastic, store bought water bottle.

The best way is 1/4 cup of vinegar and 1/2 of baking soda=82.02g ration=100/71.4
thanked the writer.
Lets see...
CH3COOH + NaHCO3 -> H2O + NaOCOCH3 + CO2
well, that means that 1 mol of vinegar + 1 mol of baking soda is all we need, all I have to do is find the molecular weight of each thing...
Vinegar=60.06g Baking soda=84.02g
which means that the ratio is...
For every 100g of baking soda, 71.4 grams of vinegar
:D hope that helps

Okay! I like your answer as well because you got all the forms.
We tested the half ratio, more vinegar worked better, but I added some black rasberry jello powder which was 1:4 ratio to the baking soda, and 9 packs of cherry pop-rocks candy. He he he he he, (anything I found in the pantry that sounded good), shook the dry mixture in a short water bottle and then poured in the vinegar (which you have to keep adding for more continuous action-only downfall), but our last test-run turned out pretty well ;) The coolest part is the pop-rocks keep popping for A WHILE AFTER THE ERUPTION, it's been 10 minutes and they are still going.   Oh, no water, no detergent, no food coloring (the jello and pop-rocks took care of that)
Yep yep yep..., so there is my new found secret.
I expect her to bring home an A+ on this.  :) Good luck to all others as well.

1.Go outside or prepare for some clean-up inside
2.Put the container into the volcano at the top
3.Add two spoonfuls of baking soda
