Question

What is the charge on the polyatomic ion hydrogen carbonate?

Answer 1

Hint: We have to know that the atoms are generally divided by so many types depending on the number of the atom count. The total charge on the molecule is the sum of the charges on all the participating atoms. The symbol of hydrogen carbonate is \[{H_2}C{O_3}\].

Complete step by step answer:
We have to remember that the formation of hydrogen carbonate is the carbon dioxide that reacts with water to form initial carbonic acid as well as hydrogen carbonate.
The reaction for formation of hydrogen carbonate, dry ice is to react with water. The chemical formula of dry ice is \[C{O_2}\] and water is \[{H_2}O\].
 \[{H_2}O + C{O_2} \to {H_2}C{O_3}\]
As we know that the hydrogen carbonate is dissociated and to form hydrogen ion and carbonic anion.
The reaction of dissociation of hydrogen carbonate,
\[{H_2}C{O_3} \to {H^ + } + HC{O_3}^ - \]
The charge on the polyatomic ion in hydrogen carbonate is \[HC{O_3}^ - \] .

Additional Information:
The number atom is equal to one, the king of the atom is called monatomic molecules. The number of atoms is equal to two, that kind of the atom is called as diatomic molecules. The number of the atom count is equal to three is called triatomic molecules. The number of the atoms in the molecule is equal or greater; the four are called polyatomic atoms. The polyatomic ion is nothing but the number of the atoms in the ion is equal or greater than four.

Note: We also remember that the atom is made up of the electrons, protons and neutrons. In an atom, neutrons and protons are present in the centre of the atom, and are called nuclei. The electrons revolve around the nucleus in the atom. The atom is one of the tiniest particles. Atom is the unit cell of the molecule.
