A molar solution (M) is produced by dissolving a gram molecular weight of a water-solute substance in enough water to make a liter of solution.

Molarity

Weight of a substance in grams equal in number to the weight of the substance in atomic weight units

Molar mass (M)

Small particles suspended in water and are a mixture of two phases of matter

Colloids

One ppm is 1 part in 1 million or the value is equivalent to the absolute fractional amount multiplied by one million.

Parts per million

The difference between a molar and molal solution is that molal’s final volume of solution may be greater than 1 liter depending on the solute.

Molality

Subtopic of colloid property that is the effect of light scattering on particles in colloid systems

Tyndall effect

Subtopic of colloid property that is the random moving of particles suspended in a fluid

Brownian movement

Colloid property where all the suspended particles possess either a positive or a negative charge

Electrical properties

Colloid property that has to do with different sizes of molecules passing through a filter paper

Filtration properties

Colloid property with a subtopic involving the effect of light scattering on particles in colloid systems

Optical properties

Colloid property with a subtopic involving the random moving of particles suspended in a fluid

Kinetic properties
