what is a good ratio for baking soda and vinegar for a 2 L bottle rocket car?

vinegar is a weak acid so it will not disociate fully to react with the bicarbonate,something like this does not need the exact calculation for the reaction,you could use a strong acid if weight is an issue otherwise use at least 10 times by volume more vinegar that soda

I would say an isotonic solution of salt (0,9%) is good enough and no sodium bicarbonate is needed.

you can use an orange juice contrainer as the base of the car and for the wheels...anything round shaped.

Citric acid is triprotic so you have the ratio you need already written.  You last + sign should be an arrow and you are making salt and water from there.  To do the calculation you already have what you need from the reaction.  YOu need data as far as the amount of apple juice and concentration and amount of base.

at least half a gallon.

hey hun....i have red before to mix a little (tsp) of baking soda with a glass of water....i have never tried it before but if you get adventuress and try it let us know how it work out....love daisy

of course gas but if cant get that any flex fuel additive sold at auto stores. (or can order by gallon for you) with common ratio of 1 pint additive to 5-10 gals coco or other subsitute. theyll know which is best. also if use gas youd want 1 gal per10 gals of your substitute fuel.

When I do this, I use mostly sodium bicarbonate and very little water (just enough to dissolve the baking soda). The point is that the acid is very damaging, so you want to make darn sure that you've neutralized it. The baking soda is not dangerous, so you don't worry if you use excess baking soda. \n\nWhen you're done, and have neutralized the acid, you rinse everything thoroughly with plain water.

The answer is 2.5 gallons of ethanol.  Check out the link.

vinegar and lots of water

Indeed, you start a nice chemical reaction. Baking soda is a base and Vinegar an acid. They neutralize each other producing CO2 (a gas), NaC2H3O2 (a salt), and H20 (water).\n\nHow cool is that? Do it in a bottle and cork it (point the cork away form you and your friends).\n\nGet an "A".

Baking soda will neutralize the sulfuric acid.\n\nBatteries do not produce sulfuric acid!\nSulfuric acid is placed in the battery to generate eletricity through electrolysis.\n\nAs far as making the lead useable, they do recycle car and lead/acid batteries, is that useful enough?  \n\nIf you are planning on opening a car battery you are asking for potential injury or death.  You could cause an explosion, end up blind, maimed, or possibly dead.  I have seen batteries explode and it is not pretty.  I have had a few rupture/burst very close to my face while working on cars, that is not a nice situation to be in either.  Fortunately I wasn't hurt except for superficially, but batteries can be very dangerous.\n\nIf you need lead metal for a project or experiment, go ask a tire shop for their old, throwaway wheel weights.  They usually have tons of them and don't mind giving them away.\n\nDivers used to use lead weighted belts to keep them from floating, maybe there's some salty old sea man around a dock or something who knows where you can find some.

solution...Bicarbonate and sodium. :)

Here's a tip, leave the baking soda and something a bit complicated.  Like a Lemon battery. I have a site that has choc loads of interesting things.  Most of all very simple.

Ammonia, baking soda.

Use the box of baking soda as a weight to provide torque to propel the vehicle and to wind the rubber bands. Once the box hits the ground, the hook can fall off and the rubber bands will unwind and propel the vehicle back the 1m.\n\nYou are using the box of baking soda as potential energy converted to kinetic energy to wind the bands and propel the vehicle.
