| Term | Definition |
|---|---|
| Solution | Homogenous mixture, substance + solvent = solution. |
| Solvent | The substance present in greater amount. Water is the most common. |
| Solute | The substance that is in lesser amount. Ex: Salt water - salt is the solute, water is the solvent |
| Hydration | Water molecules surround each ion |
| Electrolytes | Solutes that dissolve in water that conduct electricity. |
| Nonelectrolytes | They dissolve in water as molecules and do not conduct electricity. |
| Alkanes | Hydrocarbon family makes better fuels and nonpolar solvents. |
| CH3-CH2-CH2-CH2-CH2-CH2-CH2-CH3 | IUPAC name is Octane |
| Hypertonic | A solution that has a higher pressure (and concentration of ions) in solution than body fluids. |
| CH3-CH2-CH2-CH2-CH3 | IUPAC name is Pentane |
| Covalent bond | Organic compound primarily possess this type of bond |
| Colloids | Mixtures in which the solute particles scatter light, pass through filter paper, but do not pass through a semipermeable membrane. |
| Bases | Turns red litmus paper blue, bitter taste, feels slippery and is found in oven cleaners and bleach. |
| Crenation | Shriveling of a cell due to water leaving the cell when placed in hypertonic solution. |
| Molarity | Ratio of the number of moles of solute per liter of solution. |
| Nonelectrolyte | A solution that does not conduct an electrical current. |
| Saturated | When a solution contains the maximum amount of solute that it can dissolve at the current conditions of temperature and pressure. |
| Hydrocarbons | Organic compounds which only contain these elements. |
| Covalent | Generally have a higher melting point |
| Weak electrolyte | Gives only a few ions when dissolved in water |
| Acidosis | Forward shift in the equilibrium causing excess acid production |
| Alkalosis | Excess base (or alkali) |
| Alkanes | Hydrocarbons which contain only single bonds are called alkanes. |
| Alkenes | Unsaturated hydrocarbons having one double bond |
| Alkynes | unsaturated hydrocarbon which has at least One carbon—carbon triple bond between two carbon atoms |
| Aromatics | Based on the benzene ring, C6H6 |
| Ethyl group | CH3CH2 |
| Methyl group | CH3 |
