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 |
