Question

Baking soda is a compound.
A. True
B. False
C. Either
D. Neither

Answer 1

The components of the baking soda need to be considered for understanding if baking soda is a compound of different elements or a mixture of those elements. Therefore, the characteristics of compounds need to be defined for proving that the elements are arranged in that manner.

Complete answer: Baking soda is the common name for sodium bicarbonate salt $\left( {NaHC{O_3}} \right)$. The white powdered compound is a crystalline structure which is used for several purposes and the compound is formed using several elements. The elements that are involved in the formation of baking soda are Sodium $\left( {Na} \right)$, Hydrogen $\left( H \right)$, Carbon $\left( C \right)$ and Oxygen $\left( O \right)$. These elements are arranged in the specific ratio of all the elements which forms the given compound. This is the condition in the pure form of baking soda and since all the elements are arranged in a specific ratio, it is known as a compound. If the elements were mixed in a disorderly manner, it would be considered a mixture. Therefore, the statement that baking soda is a compound is True. The compound can also be subjected to decomposition where the sodium bicarbonate forms sodium carbonate. Some of the common uses of baking soda is that the compound is used for the treatment of itching of the skin and reduces the chances of heartburn which occurs as a result of acid reflux from the stomach. Apart from this its main function is being used in bakeries and cooking purposes.

Hence the correct option is (A).

Note: Baking soda if present in impure form as the white powder might contain both baking soda and sodium carbonate formed after partial decomposition. If the baking soda is not pure, there can be a mixture of both only, but the pure form is present as a compound structure.
