Baking powder (baking soda + some acid salts) will release CO2 (carbon dioxide gas) when placed in water. So, even though, in theory, all reactions are reversible, it is not likely that baking powder in water is reversible once the CO2 gas has formed.

Irreversible... You could distill a cup of prepared coffee - until all the water boils off, but you would never get back the original coffee powder, or granules.

It is reversible. You can allow the water to evaporate, leaving the salt behind.
no it is irreversible change
Nearly, a physical change creates a substance and this is reversible. For example, ice-water. Water-steam. These are all reversible. A chemical change is irreversible. For example, baking a cake; you cannot get the original ingredients back again.
