Chapter 19 - Acids And Bases Flashcards
What is the term for a substance that dissociates in water to produce hydroxide ions?
Base (Arrhenius Definition)
What is the term for a solution in which the pH remains relatively constant, even when small amounts of acid or base are added?
Buffer
What is the term for compounds that have more than one ionizable hydrogen to release?
Polyprotic Acid
What is the term for the substance that dissociates in water to produce hydrogen ions (H+)?
Acid (Arrhenius definition )
What is the term for a solution that changes color as the pH changes?
Indicator
What is the term for the remainder of the original acid after it donates it’s hydrogen ion?
Conjugate base
What is the term for the process of adding a known amount of solution of know concentration to determine the concentration of another solution?
Titration
What is the term for any substance that can accept hydrogen ions?
Base (bronstead-Lowry definition)
What is the term for the amount of acid or base that can be added before a significant change in pH?
Buffer capacity
What is the term for what contains the “carboxyl” group sometimes several of them?
Organic acids
What would you add to a substance if you wanted to keep the pH of that solution consistent?
Buffer
What can you use in order to determine the concentration of an unknown solution?
Titration
