Mixtures, Solutions and Salts

Solutions  A solution is a mixture of two or more substances that is homogeneous at the molecular level.  Homogeneous means the particles are evenly distributed.

Suspensions  In a mixture called a suspension the particles can range widely in size.  Muddy water, will settle when it is left still for a period of time, so it is heterogeneous

Colloids  Colloids are mixtures, and look like solutions, but their particles are too small to settle to the bottom of their container over time.  Examples of colloids are mayonnaise, egg whites, and gelatin.

Types of mixtures  How can you tell the difference between a solution, a colloid and a suspension? Do particles settle? Will filtering separate particles? Clarity SolutionsNo Very Clear ColloidsNoOnly w/ Special Equipment Cloudy SuspensionsYes Cloudy

Solutions  A solution contains at least two components: a solvent, and a solute.  The solvent is the part of a mixture that is present in the greatest amount. Which of these is the solvent?

Water and solutions  When the solute particles are evenly distributed throughout the solvent, we say that the solute has dissolved.

Solubility  The term solubility means the amount of solute that can be dissolved in a volume of solvent.

What is a SALT? A salt is a neutral substance produced from the reaction of an acid and a base. Composed of the negative ion of an acid and the positive ion of a base. Examples: NaCl, KCl, MgSO 4

Table Salt (NaCl)

Potassium Chloride (KCl) Used for making fertilizers

Magnesium sulfate (MgSO 4 )  MgSO > Mg 2+ + SO 4 2-  Used in fertilizer to increase Mg in the soil. Also used in bath salts to increase how well the body floats
