Equilibrium Reactions with ICE Box Method
Acid Dissociation Problems Using the ICE Table Method
Acid Dissociation Constant (Ka) is a measure of the strength of an acid in solution. It is the equilibrium constant for an acid dissociation reaction.
example with an ICE Table:
5.00M HNO_2 Dissociates into H+ and NO_2- according to its acid dissociation constant Ka=4.0*10^-4. Determine the equilibrium concentration of HNO_2, H+, and NO_2-.
Step 1) Put in initial concentrations.
Step 2) Use stochiometry coefficients to determine what change would occur if X amount of the acid dissociated.
Step 3) Add down columns to get equilibrium values.
Step 4) Substitute the equilibrium values into equilibrium equation.
