TermDefinition
concentration the amount of material dissolved in a measure of a liquid; adding more material will make solution more concentrated-UNTIL solution gets saturated
dilute to make a solution less concentrated, usually by adding more liquid
volume the three-dimensional space occupied by liquid
chemical reaction when two or more mixtures are mixed together and a change occurs, such as: bubbling, temperature change, property change, new material is formed (like a precipitate)
precipitate solid material that is made as a product of a reaction
change the process of becoming something new
reactants the chemicals that react when mixed together
mixture when you stir two or more materials together; ALL mixtures can be separated
solution a SPECIAL mixture made when material dissolves in water (dissolving MUST happen!
property characteristics of an object; something you can observe such as color, shape, size, and texture
dissolving process when material spreads throughout another material; seems to disappear; Temperature effects dissolving (Heat makes material dissolve faster.)
crystal the solid of a material that can be identified by its properties such as shape, color, and pattern; The salt crystal is square with an X corner to corner. (Other crystals: sugar crystals, snowflake crystals)
evaporation the change from a liquid to a gas; this is one way to separate some solutions
salt solution one part of the salt solution is the solvent and the other part is the solute; can be separated by evaporating
solute the material that dissolves
solvent the liquid into which the solid material goes into (The universal solvent is water!)
saturation when solid material (the solute) is added until NO more will dissolve AND there is material on the bottom
solubility the property substances have of dissolving in solvents, such as the solubility of salt in water
