sodium chloride
« on: February 01, 2009, 06:40:52 PM »
Hi Everyone,

Need little help if possible,
When solution sodium-chloride and  distilled water are evaporated , what is the name of the residue remaining after evaporation, and the name of the formula for the residue ? 

Thanks a lot?

What is removed by evaporation? Is this a physical or chemical change?

Good question.

I did not know that the remaining contents of a solution has a name and formula. Interesting.
