Valency of HCO3

The valency of a compound refers to the number of electrons that an atom gives up or accepts when it forms a chemical bond. In the case of HCO3, which is also known as bicarbonate, the valency can be determined by analyzing the Lewis structure of the molecule.

Lewis Structure of HCO3

The Lewis structure of HCO3 shows that the molecule consists of one carbon atom, three oxygen atoms, and one hydrogen atom. The carbon atom is at the center of the molecule, and each of the three oxygen atoms is bonded to it. One of the oxygen atoms is also bonded to the hydrogen atom. The Lewis structure for HCO3 can be written as follows:

O

Valency of HCO3

Based on the Lewis structure of HCO3, it can be determined that the valency of the molecule is -1. This is because the molecule has one more electron than it has protons. The valency of the hydrogen atom in HCO3 is +1, while the valency of the oxygen atom is -2. The valency of the carbon atom in HCO3 is +4.

Conclusion

In conclusion, the valency of HCO3 is -1. This is because the molecule has one more electron than it has protons. The valency of the hydrogen atom in HCO3 is +1, while the valency of the oxygen atom is -2. The valency of the carbon atom in HCO3 is +4. Understanding the valency of a molecule is important in determining its chemical properties and how it reacts with other molecules.
