Acid- Base Equilibria Flashcards
How did Arrhenius define an acid
A substance that ionises/ dissociates in an aqueous solution to produce H+ (aq) ions
How did Arrhenius define a base
A substance that ionises/ dissociates in an aqueous solution to produce OH- (aq) ions
If you bubbled HCl through water what would happen to the conductivity of water and why
The conductivity would increase due to the formation of H+ and Cl- ions formed through the dissociation of HCl
Define monoprotic
A substance that only releases one H+ ion on dissociation eg. HCl (it can also be monobasic)
The same idea applies for diprotic and triprotic
How did Brønsted-Lowry define an acid
Proton donors
How did Brønsted-Lowry define bases
Proton acceptors
What is a conjugated acid/ base pair
A pair of species that differ by one proton
Do strong acids have weak or strong conjugated bases
Weak bases (and vice versa for weak acids)
What can a redox reaction be seen as
A competition for electrons
What can an acid- base reaction be seen as
A competition for protons
Write out a hydroxonium/ hydronium ion
H3O +
Name the H3O+ ion
Hydroxonium/ hydrodium ion
How did Lewis define an acid
An electron pair acceptor
How did Lewis define a base
An electron pair donor
What is a substance called if it can act as both an acid and a base
Amphoteric
