Buffers
Resist change in pH
must contain weak acid & conj base or weak base and conj acid
Henderson-hassel balch equation
pH= pKa + log(base/acid)
buffer capacity
how much acid/base a system can buffer before becoming ineffective
Equilvance
moles acid = moles base
end point
physical change that occurs that signals equilvance was reached
Ksp
solubility product
NOT the same as solubility
if a participate was formed,,,,,
Q>K
Amphoterism
metals that can dissolve in strong acids or bases because they can act as acids or bases
ex: Al³+, Zn+2, & Sn+2
strong acid/strong base

weak acid/strong base

weak base/strong acid
