Science 7 Lesson 2 Quarter 1: Solutions, Solubility, and Concentrations

A substance made by mixing other substances together

Mixture

Mixture that has 2 or more phases of matter which are usually visible

Heterogenous mixture

a mixture where the particles of one substance are evenly dispersed throughout another substance

colloid

insoluble particles are suspended in a liquid/gas

suspension

2 types of heterogenous mixture

colloid, suspension

mixture that has one phase with uniform composition throughout

homogenous mixture

composed of a solute & solvent

solution

a substance that can be dissolved, the smaller amount

solute

the substance that dissolves substances, the greater amount

solvent

whenether a certain solute can be dissolved in a specific solvent, the max amount that can be dissolved

solubility

factors affecting solubility

Temperature, pressure, surface area, stirring

when the solute mixes with the solvent

dissolution

how fast a solute dissolves

rate of dissolution

factors affecting rate of dissolution

temperature, amount of solute, pressure, particle size/surface area

the amount of solute dissolved

concentration

solutions with small amounts of solute

diluted solution

solutions with large amounts of solute

concentrated solution

contains less solute than a saturated solution

unsaturated solution

when the solvent has already dissolved the max amount it can

saturated solution

a solution that contains more than the expected max of solute

supersaturated solution
