Question

The chemical name of baking soda is sodium _______.

Answer 1

Hint: Baking soda involves an anion that can give carbon dioxide gas upon the reaction with certain reagents. The anion that is present in the baking soda has an overall charge of (-1).

Complete step by step solution:
The chemical name shows the presence of the ions or the atoms present in the compound. We know that there are different names for ions of same metals having different oxidation states. Thus, chemical names give a compound a distinct identification.
-Here, we are being asked about the chemical name of the baking soda. So, we will find the chemical name of the baking soda.
-Note that baking soda is the common name of this compound.
-Whenever there is the word ‘soda’ used in the inorganic compound, it corresponds to the presence of sodium ions in the compound. So, by this we can predict that sodium is present in baking soda which is also given in the question.
-Now, we know that sodium is a cation and as it is an ionic compound, we need an anion that completes the structure. Now, soda is related to carbon dioxide gas. It relates to the compound that can give carbon dioxide when allowed to react with certain reagents.
-The anion that can give carbon dioxide gas upon reaction is $C{O_3}^{2 - }$ and $HC{O_3}^ - $. Baking soda includes $HC{O_3}^ - $ as an anion.
-As hydrogen is there with the carbonate ion, the $HC{O_3}^ - $ ion is called bicarbonate ion.

So, we can say that the chemical name of the baking soda will be sodium bicarbonate.

Note: Do not get confused between the washing soda and baking soda. Washing soda is $N{a_2}C{O_3}$ (Sodium carbonate) and it is not used in eating. Baking soda is $NaHC{O_3}$ (Sodium bicarbonate) and it is used in eating.
