Acids And Bases Flashcards
Arrhenius theory
An acid is a substance that ionizes in water to produce hydrogen ions.
A base is a substance that dissociates in water to produce hydroxide ions.
Brønsted-Lowry theory
An acid is a proton (H^+) donor
A base is a proton (H^+) acceptor
Strong acid
An acid that ionizes completely in an aqueous solution
Strong base
A base that dissociates completely in an aqueous solution
Weak acid
An acid that only ionizes partially in an aqueous solution
Weak base
A base that only dissociates partially in an aqueous solution
A concentrated acid
A large amount of absolute dissolved in a small amount of water
A dilute acid
A small amount of solute dissolved in a large amount of water
Salt
A substance in which the hydrogen of an acid has been replaced by a cation
Neutralization
The point where an acid and base have reacted so neither is in excess. Also called the equivalence point
Indicators
A substance that changes colour depending on the pH of a solution
Solution
A homogeneous mixture of solute and solvent
A standard solution
A standard solution has a know concentration and it will remain constant for a while
Amphoteric / Amphiprotic substance
A substance that can act as either an acid or a base.
pH
A number that indicates the degree of acidity of a solution.
