Title: Polarity of Molecules
Post by: click here on May 03, 2006, 07:52:54 PM

Sometimes i just hate  >:( google because i can't find what i need so i decided to ask here.

How do you find out the polarity of Sodium Sulfate, Ammonia, Carbon Tetrachloride, Methane, and water.  I need to know whether or not one substance would dissolve in another.

Thanks in advance for anyones help.

Sodium sulfate is an ionic salt.
Methane and carbon tetrachloride are almost identical when it cames to assessing polarity. Think about molecules geometry.
Water and ammonia - also think about geometry.
