Question Answer
what suppresses the ionization of a weak acid or a weak baseThe presence of a common ion
common ion effectthe shift in equilibrium caused by the addition of a compound having an ion in common with the dissolved substance
molaritymoles per liter
k(sub)aequilibrium constant
what does ph stand fornegative log of hydrogen concentration
pkanegative log of equillibrium constant
Henderson-Hasselbalch equationpH = pKa + log([conjugate base]/acid)
M times L ismoles
buffer solution is a solution ofA weak acid or a weak base and The salt of the weak acid or weak base
bronsted acids areproton donators
about weak acidsdon't ionize fully in water
molarity vs molalitymoles/liters vs moles/kg

Question Answer
what is -log of the xph
constituents of buffer solutionweak acid/base and salt
kaacid ionization constant
to find molesM times L
first step to find ohfind moles
find oh from pohOH=10^-poh
for Qcmultiply molarities
