What does baking powder do that baking soda (sodium bicarb) alone doesn't do?
Apart from disodium diphosphate (which sounds like a fertiliser) and a bit of flour in baking powder what is the advantage in cooking in using one over the other?

Baking Soda (sodium bicarbonate) is an alkali.
The other ingredients (not always the same), are acid salts.
When these two combine, the cause a froth and bubble, which releases co2 and cause the dough/batter/etc to rise.
You can use just baking soda, if there are acidic ingredients in you recipe, i.e. orange, lemon, pineapple etc etc. But baking soda is not a replacement for baking powder.
