| mixture | material composed of two or more substances that are physically mixed together but not chemically combined |
| solution | mixture in which all the components are evenly distributed |
| solute | the substance that is dissolved in a solution |
| solvent | the substance in which another substance is dissolved to form a solution |
| acid | substance that releases hydrogen (H+) ions when mixed with water |
| base | substance that releases hydroxide (OH-) ions when mixed with water |
| pH scale | measurement system to indicate the concentration of hydrogen (H+) ions in a solution |
| pH 7 | neutral solution, pure water, hydrogen ions (H+) = hydroxide (OH-) ions |
| pH below 7 | acidic solutions, hydrogen ions (H+) > hydroxide (OH-) ions |
| pH above 7 | basic solutions, hydrogen ions (H+) < hydroxide (OH-) ions |
| buffer | weak acids or weak bases that react with strong acids or bases to prevent sharp and sudden changes in pH |
| Sufuric acid | car batteries,dehydrating agent, skin burns |
| phosphoric acid | industry,detergent, diluted has sour but pleasant tast |
| nitric acid | make explosives, concentrated-colorless,turns yellow |
| hydrochloric acid | colorless gas,strong acid,used industry |
| sodium hydroxide | most widely used base |
| hydrogen chloride in water | HCL + H2O >H3O +CL |
| hydroxide ion | what acid produce in water |
| hydronium ion | what you get when you put water and hydrogen ions together forming H3O |
| strong acid | acid with low ph |
| strong base | acid with high ph |
| neutralization reaction | reaction between acid and base |
| salt | (-)ions form the acid combine with (+) ions from a base |
