Main ingredients are - Baking soda (NaHCO_{3}) and an edible acid like tartaric acid.

The function of each ingredients are -

= Baking soda ( sodium Hydrogen Carbonate) releases carbon dioxide (CO_{2}) gas when heated which makes cakes soft and fluffy.

= Tartaric acid is used to neutralize bitter taste of salt by reacting with Na_{2}CO_{3} formed by the heating of NaHCO_{3}

= 2NaHCO_{3}\overset{Heat}{\rightarrow}Na_{2}CO_{3}+H_{2}O+CO_{2}
