Solubility

Soluble Sugar is soluble in water. Translation: Sugar dissolves in water. The solute particles are more attracted to the solvent than they are to each other. Examples?

Sugar is soluble in water.

Insoluble Insoluble – not able to be dissolved in a particular solvent. Ex. Fat droplets in milk. The solute particles are more attracted to each other than they are to the solvent.

Oil is insoluble in water.

Nail Polish Soluble in water ? Or Insoluble? Soluble in acetone ? Or insoluble?

Chlorophyll (grass stains) Soluble in water ? Or Insoluble? Soluble in rubbing alcohol ? Or insoluble? /qxp73865_333181_sespi der/rite_aid/isopropyl_rub bing_alcohol_70.htm

Concentration

Concentrated Solution (lots of solute) Dilute Solution (relatively little solute) How do you describe what is in between?

Concentrated or Dilute?

Compared to this one…

Concentration How do you know what to compare it to? We use numbers to describe how concentrated or dilute something is. This is called the concentration. The concentration tells us exactly how much solute is in a certain amount of solvent (or one tube of water).

“Make me a green solution with a concentration of 3.”
