Commonly Tested Lewis Structures

We draw Lewis Structures to predict:

-the shape of a molecule.

-the reactivity of a molecule and how it might interact with other molecules.

-the physical properties of a molecule such as boiling point, surface tension, etc.

Drawing the Lewis Structure for SO42- (Sulfate Ion)

Sulfates (salts with the SO42-) are frequently used in industry and biologically.

A commonly used sulfate is sodium lauryl ether sulfate found in shampoo, toothpaste, etc.

For example, MgSO4 is also known as Epsom Salts.

There are 32 valence electrons available for the Lewis structure for SO42-.

Video: Drawing the Lewis Structure for SO42-

It is helpful if you:

  • Try to draw the SO42-Lewis structure before watching the video.
  • Watch the video and see if you missed any steps or information.
  • For more help, watch this general tutorial on drawing Lewis Structures for compounds like the Sulfate ion.
