| solvent | usually water which dissolves the other substance placed in it |
| solute | this is dissolved in a solution |
| saturated solution | solution in which no more solute can dissolve |
| concentration | the comparison of the amount of solute in equal volumes of solvent in different solutions |
| What to look for to determine if a chemical reaction has taken place | temperature change, color change, energy released or taken in, formation of a precipitate, bubbles indicating a gas is being formed |
| chemical reaction | when two or more substances are mixed together and create new substances |
