acids and bases Flashcards
bronsted acid
proton donor
strong acid
acid which ionises almost completely in an aqueous soln
eqm very far right
large Ka
HNO3, HCL,H2SO4
bronsted base
proton acceptor
weak acid
acid that only ionises partially in an aqueous soln
eqm lies far left
small ka
ionisation
reaction of a molecular substance with water to produce ions
dissociation
splitting of an ionic compound into its ions
polyprotic acids
able to donate more than one proton
dilute acid
small no. of moles in acid
strong base
base that dissociates almost completely in an aqueous soln
high Kb value
group 1 hydroxides
weak base
base that ionises partially in an aqueous soln
low Kb value
test for strong or weak base
conductivity
test for strong or weak base
conductivity
strength of an acid/base
independent of concentration of soln
concentrated acid/base
contains very large amount of acid/base than water in soln
has relatively more dissolved solute than a dilute soln
conjugate base pairs
1 product and 1 reactant, 1 H+ difference
stronger an acid/base- weaker its conjugate
