What is the difference between sulfur trioxide and sulfite?
The key difference between sulfite and sulfur trioxide is that sulfite is an ionic compound having the sulfate (IV) anion whereas sulfur trioxide is a non-ionic compound. Sulfite and sulfur trioxide are chemical compounds containing sulfur atoms. Sulfur trioxide is an inorganic compound having the chemical formula SO3.

How many resonance structures does SO3 2 have?
Answer: (SO3)2- has 3 resonance structures, one for each structure that is formed when sulfur makes a double bond with oxygen.

Why does SO3 have a 2 charge?
Sulfite () is an ion where it has a sulfur atom with oxidation state +4, and 3 oxygen atoms (each being -2) so when these are combined, you get an overall charge of -2.
What is the difference between SO3 and SO3 2?
In SO3 there are three double bonds, and no lone pairs at sulfur. Adding two extra electrons changes that by giving two more electrons to sulfur. SO3 is sulfate trioxide, while SO3 -2 is called the sulfite ion.
What is the difference between SO3 and SO32?
SO3 does not have the extra 2 electrons (SO3) 2- has 2 eletrons extra. In SO3 there are three double bonds, and no lone pairs at sulfur. Adding two extra electrons changes that by giving two more electrons to sulfur. SO3 is sulfate trioxide, while SO3 -2 is called the sulfite ion.
Why SO3 2 is trigonal pyramidal?
To minimise repulsion they take an appropriate form,each oxygen has 60° between them and each oxygen atom has 120° (not sure)with the sulphur atom. Thus they form a trigonal pyramidal shape and that’s what Valence Shell Electron Pair Repulsion Theory says!!!
What are all resonance structures for SO3?
Click to expand… There are three major resonance structures for SO3. These are the equivalent structures where there exist one S=O bond and two S-O bonds. The fourth resonance structure with three S=O bonds is noncontributory due to reasons beyond the scope of MCAT chemistry.
What is the geometric shape of SO3?
The molecular geometry of SO3 is trigonal planar with symmetric charge distribution on the central atom.
Does SO3 have a resonance structure?
Answer: (SO3)2- has 3 resonance structures, one for each structure that is formed when sulfur makes a double bond with oxygen.
How to draw a Lewis structure?
To draw a Lewis structure, add up the number of valence electrons from all atoms, determine how many electrons are needed to satisfy the octet rule, and find the number of chemical bonds in the molecule. Choose a central atom and draw a skeletal structure around it.
