Question map
Which of the following is not correct about Baking Soda ?
Explanation
Baking soda, chemically known as sodium bicarbonate (NaHCO3), is a mild, non-corrosive basic salt [1]. Unlike strong bases such as sodium hydroxide, it is safe for household use and does not cause corrosion. It has several practical applications: it is used in soda-acid fire extinguishers because it releases carbon dioxide when reacting with acid, and it is added to food like gram or dal for faster cooking [1]. Medicinally, it acts as an effective antacid by neutralizing excess hydrochloric acid in the stomach, providing relief from indigestion and heartburn. Because it is specifically described as non-corrosive in standard scientific texts, the statement claiming it is a corrosive base is incorrect [1]. Its mild alkalinity (pH around 8) makes it suitable for cleaning sensitive instruments and for use in personal care products.
