Web• The Common Ion Effect • Buffer Solutions. The Common Ion Effect Common Ion Effect: is the shift in equilibrium caused by the addition of a compound having an ion in common with the dissolved substance. WebThe common ion effect is when a given ion is added to a mixture at equilibrium that already contains the given ion. This causes the equilibrium to shift away from forming more of that ion. ... the pH value will resist drastic changes. Once these concentrations are exceeded, the buffer effect of the solution will no longer function, causing ...
Common Ion Effect and Buffers in Acid-Base Equilibria
WebThe "Common Ion Effect": The dissociation of a weak electrolyte is decreased by adding to the solution a strong electrolyte (i.e. a salt) that has an ion in common with the weak electrolyte Example Acetic acid (CH 3 COOH) is a weak acid with the following ionization reaction: CH 3 COOH + H 2 O ⇔ H 3 O + + CH 3 COO-Ka = 1.8 x 10-5 WebWhy is Common Ion Effect Important? • To make buffers • Buffers resist changes in pH • When small quantities of strong acids or strong bases are added to a buffered solution, … jim interagency
