Water and Solutions

Seite 1

Water is the key to nearly everything.

Water is used in most forms of chemistry.

Di-Hydrogen Monoxide:

Solutions consists of a solvent and solute.

Water is polar which makes it the best solvent in every solution

Oxygen atoms are a little more electronegative than the hydrogen atoms - this is what makes water polar. It gives the molecule a slightly negative side and a slightly positive side.

When one mixes a polar liquid with a polar solid.

The negative and positive molecules of each side attract which causes the solid to dissolve.

Aqueous Solutions:

Water does not dissolve non-ionic substances.

Water can decrease the attractions between ions of different charges. (dielectric property)

Electrolytes - loosened electricity.
