Water as a Solvent
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
Water dissolves many substances because its polar molecules surround and separate charged or polar particles from each other.
Show
Table salt dissolves in water because water molecules surround each sodium and chloride ion, pulling the ionic lattice apart.
Watch for
Water dissolves polar and ionic substances well, but nonpolar substances such as oil resist mixing into it.
