Acids and Bases Flashcards
Arrhenious acid
A substance that dissociates in water to produce H+ ions
Arrhenious base
A substance that dissociates in water to produce OH- ions
Bronsted Lowry acid
A proton donator
Bronsted Lowry base
A proton acceptor
Neutralisation
A reaction between an acid and a base forming a salt and water
Conjugate acid
formed when a base accepts a proton
Conjugate base
formed when an acid donates a proton
Conjugate pair
An acid and a base that differ by a proton
Primary standard
A substance of high Relative Molecular Mass which can be obtained in a pure stable soluble solid form
so that it can be weighed out
and dissolved in water to give a solution of known concentration
Titration
A laboratory procedure
where a measured volume of one solution is added to a known volume of another solution until the reaction is complete
pH
-log[H+]
Kw
[H+].[OH-]
Strong acid
Good proton donor or is fully dissociated into ions in a dilute aqueous solution
Weak acid
Poor proton donor or slightly dissociated into ions in a dil. aq. soln.
Strong base
A good proton acceptor or one which fully dissociated into ions in a dil. aq. soln.
