why is baking soda a base?

[Chooco]

baking soda: NaHCO3
mixing with any acid it should create water and a salt (and maybe a gas)
there's no OH in there so what binds with the H in the acid?

also, why is ammonia a base? NH3
no OH in there either.

having the members of ATOT do your Chem homework for ya?

All your base....oh never mind...

Ask your self what happens when -HCO3 or NH3 is added to water (what does it consume) and what is left?
Edit: and I think you not undrstand what a base is: a Base is simply any molecule capable of accepting a H+ in solution

Do you think that base is friendly and acid is bad?
And i am talking about chemical acid not the drug acid, we would be here longer figuring that out.

Both are equally dangerous when the ph is right, they just cancel each other out.

Acids are substances that are capable of donating a proton, and bases are substances capable of accepting a proton.

well if im not wrong....in water ...baking soda dissociates into a weak acid and strong base...i think carbonic acid and NaOH.....hence it is becos of the NaOH that the baking soda becomes basey(wrong english) in water.

Uhm...bases do NOT need to have an OH. I dunno where you get that idea from.

All that's required to be a base is: ability to accept a proton (if you doubt this...grab some vinegar and baking soda and mix them)

Because NaHCO3 = NaCO2OH. Water, H2O can also be written HOH.

Not only is it a base but it is tasty too.
