Term | Definition |
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 |
