1
New cards

effect of Ka on acid strength

large Ka (>1) = stronger acid, smaller Ka (<1) = weaker acid

2
New cards

effect of pKa on acid strength

the smaller the pKa, the stronger the acid

3
New cards

common ion effect

adding outside ions causes the rxn to shift toward reactants, decreasing solubility

4
New cards

lewis acids

accept lone ELECTRONS (Acid Accepts)

5
New cards

bronsted lowery acids

donates H+

6
New cards

arrhenius acids

make H+ in water

7
New cards

buffering capacity

the amount of acid or base a buffer can neutralize, larger concentration=larger buffer capacity

8
New cards

buffer range

pH range which a buffer can be effective (1pH unit on either side of pKa)
