Sulfur dioxide molar mass
Molar mass of Sulfur =32.066 g/mol.O2 molar mass = 16.00 x 2 = 32.00 g/mol.Molar mass of SO2 = 64.066g/mol
Polarity of SO2 molecule
In SO2 molecules, the electronegative potential of oxygen is higher than that of sulfur. As a result, oxygen exerts a stronger pull on sulfur dioxide’s covalent bonds. The side of the molecule containing both oxygen atoms is somewhat negatively charged. Whereas, the portion which has the sulfur atom has a slightly positive charge. This makes SO2 a polar molecule.In addition, the unbonded electrons on the sulfur and oxygen create repulsion between atoms.This is another cause of the polarity of the sulfur dioxide molecule.

Sulfur dioxide Effects on Humans
Sulfur dioxide is a toxic gas that can be harmful to one’s health.It can irritate the skin and mucous membranes of the eyes, nose, throat, and lungs.Its excessive amounts might irritate and induce inflammation in the respiratory system.Sulfur dioxide emissions in the atmosphere can result in the formation of additional sulfur oxides (SOx).Small particles can develop when SOx reacts with other chemicals in the environment.These tiny particles can penetrate far into the lungs and, in large enough quantities, can cause health issues.
Frequently Asked Questions (FAQs)
Some of the frequently asked questions are given below. If you have any questions, feel free to comment or send an email to hello.moisesparabebesweb.com
1. How many lone pairs of electrons are present in SO2 lewis structure?
In the SO2 lewis structure, there are two double bonds between the sulfur and oxygen atoms. Sulfur atoms have one lone pair, while Oxygen atoms have two.
2. What is the biggest source of SO2?
Burning fossil fuels are the largest source of SO2 in the atmosphere.
So2 ionic or covalent ?
Because sulfur and oxygen are both non-metals, the formation of sulfur dioxide is a covalent bonding process. Two oxygen atoms encircle the sulfur atom in the middle.
