The constituents of baking powder that makes the dough to rise is
NaHCO3
NaOH
Na2CO3
NaCl
0
Explanation: Baking powder contains sodium hydrogen carbonate (\(\ce{NaHCO3}\)) and a weak acid (like cream of tartar). When heated, \(\ce{NaHCO3}\) decomposes to release carbon dioxide gas:
\(\ce{2NaHCO3 -> Na2CO3 + H2O + CO2}\)
The \(\ce{CO2}\) gas forms bubbles in the dough, causing it to expand and rise. That’s why \(\ce{NaHCO3}\) is the active constituent responsible for making dough rise.
