What happens when baking powder is added to water:
* Dissolution: Baking powder is a mixture of sodium bicarbonate (baking soda) and an acid (like cream of tartar). When added to water, the sodium bicarbonate dissolves, releasing bicarbonate ions (HCO3-).
* Reaction: The dissolved acid reacts with the bicarbonate ions, producing carbon dioxide gas (CO2), which is what makes cakes rise.
What happens when baking powder is added to lemonade:
* Similar dissolution: The sodium bicarbonate in baking powder dissolves in lemonade just like it does in water.
* Faster reaction: The acidity in lemonade is higher than in water, causing a faster reaction between the acid and bicarbonate ions. This generates more CO2 gas, making it seem like the baking powder "doesn't dissolve" because it's rapidly reacting and releasing gas bubbles.
In conclusion: Baking powder actually dissolves in lemonade, but the reaction with the citric acid in lemonade happens quickly, leading to rapid gas production and a perceived lack of dissolution.
