Hint: contains hydrogen, carbon and oxygen atoms. is composed of more than one atoms and thus, is polyatomic. Also, has one negative charge and thus, it is a polyatomic anion. Write the name of using the rules for naming polyatomic ions.
Complete step by step answer: contains a hydrogen atom and a ion.
The ion is the carbonate ion.
Thus, the name of is hydrogen carbonate.
Prefix “bi-“ is used instead of hydrogen. Thus, hydrogen carbonate is also known as bicarbonate.
Thus, the statement “formula of bicarbonate is ” is true.
So, the correct answer is “Option A”.
Additional Information: Bicarbonate ion contains three atoms and thus, it is known as a polyatomic ion. The conjugate acid of bicarbonate ion is carbonic acid .
Bicarbonate in the form of its sodium salt i.s. sodium bicarbonate is commonly known as baking soda. It is used as an antacid. It relieves heartburn, upset stomach and indigestion of acid.
Sodium bicarbonate is a rich source of carbon dioxide and thus, it is the main ingredient of baking powders, effervescent beverages and fire extinguishers.
Note:
Polyatomic ions comprise two or more atoms. One or more oxygen atoms are joined to the main atom with a charge. Ions with a positive charge are cations while the ions with a negative charge are anions.
Rules for naming polyatomic ions are as follows:
-Write the name of the first atom.
-Determine the number of anions that can be formed by adding oxygen atoms to the main atom.
-If the number of oxygen atoms is higher for an element then add suffix “-ate” and if the number of oxygen atoms is lower then add suffix “-ite”.
-If the anion contains a hydrogen atom then add the prefix “bi-“ or add “hydrogen” before the name.
Complete step by step answer:
