Term | Definition |
---|---|
Arrhenius Model | Acids produce hydrogen ions (H+) in solution Bases produce hydroxide ions (OH-) in solution |
Bronsted-Lowry Model | An acid is a proton (H+) donor A base is a proton acceptor |
Conjugate Acid | Substance that's formed when a proton is added to a base *has extra proton (H+) that it can donate* |
Conjugate Base | Remaining substance when a proton is left from an acid *could steal another proton (H+) |
Conjugate acid-base pair | Two substances related to each other by the donating and accepting of a single proton |
Strong Acid | *A reaction is not reversable *Completely dissociates *Weak conjugate base |
Weak Acid | *Only partially dissociates *Strong conjugate base |
Oxyacids | Acidic Hydrogen is attached to an oxygen atom |
Organic Acid | Carbon backbone (usually weak) |
pH | Measure of the acidity of a solution *pH=-log[H+] |
pOH | *pOH=-log[OH-] |
Indicators | Chemicals that change colors in certain pH ranges |
Titration | A technique used to determine the concentration of an acid or a base using a known concentration |
Standard Solution | One in which the concentration is known precisely |
Buret | Device used for the precise and accurate measurement of a given solution |
Equivalence Point | Point in a titration when enough titrant has been added to exactly neutralize the other |
Buffered Solution | Resists the change in pH when an acid/base is added *made by adding a weak acid and it's conjugate base* |
