| 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

| 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
🗑

| 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*
🗑
