Answer #1

3. Baking powder contains baking soda (sodium hydrogen carbonate) and sodium aluminum sulfate. Sodium hydrogen carbonate is a weak base whereas sodium hydrogen carbonate is a weak acid. When a liquid is added to this mixture, a neutralization reaction takes place. these two ingredients react to release carbon dioxide gas which causes the formation of bubbles. The rxn involved is as follows:

3 NaHCO3 + NaAl(SO4)2 → Al(OH)3 + 2 Na2SO4 + 3 CO2
