Is baking powder reversible or irreversible in water?
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.
Is baking powder reversible of irreversible in water?
Baking powder is generally considered a reversible reaction in water, as it dissolves and dissociates into its components, allowing it to react chemically when mixed with other ingredients. However, the reaction that occurs when baking powder is heated (producing carbon dioxide gas) is irreversible. Thus, while its dissolution in water is reversible, the subsequent chemical reactions during baking are irreversible.

Is a compound irreversible?
That depends on what is being mixed together. Two examples of this are: If you mix sand, gravel, and water it is reversible and you can separate the mixture back to its original three parts. If you mix sand, gravel, water, and cement powder it is not reversible as the water will react with the cement powder creating liquid cement and the sand and gravel will form concrete with the liquid cement. After a few hours the liquid cement in the concrete will set and the concrete mixture will become as hard as rock. It is now no longer possible to separate the mixture back to its original four parts.
Is baking powder a mixture or a pure substance?
