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

Heterogeneous 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, agitation, particle size or surface area in contact

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
