When baking soda and vinegar are mixed together, what gas is produced?

Answer 1

Baking soda is a bicarbonate of sodium. Vinegar is mild acetic acid which is a weak organic acid. The two will react in a neutralization reaction to produce sodium acetate, water and carbon dioxide which is the gas you see. If you want to be certain it is CO2, then bubble it over lime water (saturated calcium hydroxide) and it will turn it cloudy.

vinegar contains about 5% acetic acid by volume. acetic acid is CH3CO2H. (google that). it's the chemical that you smell. it's very pungent. Baking soda contains sodium bicarbonate. NaHCO3. That's about as odorless as table salt. You should know that if you've every been around baking soda. mix the two together and you get... 1 CH3CO2H + 1 NaHCO3 ---> 1 CH3CO2Na + 1 H2CO3 and that H2CO3 (carbonic acid) breaks down into H2O and CO2. Both are odorless. Sodium acetate (CH3CO2Na) is also very much odorless. The CO2 is the gas that evolves. H2O is liquid and sodium acetate stays dissolved in the water. So.. if you mix the right quantities of vinegar and baking soda, the odor will go away. And if you mix it slowly enough, it won't froth much either. (the frothing is due to the CO2 escaping fyi). And if you do this on a balance, then yes you could see the mass dropping as CO2 leaves the liquid and vacates into the atmosphere. how much? well... let's say you started with 25 mL of vinegar. 5% of that is 1.25 mL of acetic acid. Acetic acid has a density of 1.05 g/mL and a molar mass of 60.0 g/mole. so ... 1.25 mL acid x (1.05g / mL) x (1 mole / 60.0g) x (1 mole CO2 / 1 mole acid) x (44.0g CO2 / mole CO2) = 0.963g of CO2. and that would require... 1.25 mL acid x (1.05g / mL) x (1 mole / 60.0g) x (1 mole NaHCO3 / 1 mole acid) x (84.0g NaHCO3 / mole NaHCO3) = 1.84g baking soda ie.. you would start with about 26.8 g of vinegar and baking soda and end up loosing about 1 gram as the CO2 leaves (about 4% mass lost). Very observable with a balance. ******* as to whether or not this reaction is powerful. Indeed it can be. Depends on how much CO2 is produced and what the volume and resulting pressure is. There are 2-L plastic pop bottle rockets that are sold based on this reaction. And if you had a rigid enough container, you could cause an explosion and serious injury. And acetic acid is an acid and therefore needs to be treated with respect. It can dissolve skin and other tissues resulting in a chemical burn. ******* not a chemist, just a Ph.D. Chemical Engineer.

Answer 3

Baking Soda, (sodium bicarbonate) is a naturally occurring substance that is present in all living things--it helps living things maintain the pH balance necessary for life. Baking Soda is made from soda ash, also known as sodium carbonate. It is dissolved into a solution through which carbon dioxide is bubbled, and sodium bicarbonate precipitates out forming Baking Soda. It is pure enough (more than 99%) to be listed in the United States Pharmacopoeia (USP) since 1848.

Answer 4

Almost certainly carbon dioxide, but also potentially water vapor if it is hot enough.

Answer 5

CO2
