Common Ion Effect


Definition

Definition

  • Shift in equilibrium that occurs when we add an ion that is a component of an equilibrium reaction


Example

Example

  • Suppose that we add .100 mole of sodium acetate, NaC2H3O2 , to 1 L of .100 M solution of acetic acid, HC2H3O2 . What is the pH of the solution?


Example1

Example

  • Calculate the fluoride concentration and pH of a solution containing .10 mole of HCl and .20 mole of HF in a liter of solution.


Example2

Example

  • Calculate the % dissociation of HF in a solution containing 1.0M HF and 1.0M NaF.
