Chem 2 ch 16

chapter 16

common ion effect the shift in equilibrium caused by the addition of a compound having an ion in common with the dissolved substance
What suppresses the ionization of a weak acid or weak base the presence of a common ion
Henderson-hasselbalch equation ph= pKa+ log [cojugate base]/[acid]
What is a buffer solution? 1. A weak acid or weak base and 2. the salt of the weak acid or weak base BOTH MUST BE PRESENT!
What does a buffer solution do? it has the ability to resist changes in ph upon the addition of small amounts or either acid or base.
What is a titration? It is when a solution of accurately known concentration is gradually added to another solution of unknown concentration until the chemical reaction between the two solutions is complete.
Equivalence point the point at which the reaction is complete
Indicator substance that changes color at (or near) the equivalence point
Ksp product solubility constant
molar solubility (mol/L) is the number of moles of solute dissolved in 1 L of a saturated solution
Solubility (g/L) is the number of moles of solute dissolved in 1L of a saturated solution
What decreases the solubility of a salt? the presence of a common ion
complex ion is an ion containing a central metal cation bonded to one or more molecules or ions
formation constant or stability constant (Kf) is the equilibrium constant for the complex ion formation
