WebA common method of making a solution of a given concentration involves taking a more concentration solution and adding water until the desired concentration is reached. This process is known as dilution. We can relate the concentrations and volumes before and after a dilution using the following equation: M₁V₁ = M₂V₂ where M₁ and V₁ ... WebAt equilibrium the concentration of I 2 is 6.61 × 10 −4 M so that. The ICE table may now be updated with numerical values for all its concentrations: Finally, substitute the equilibrium concentrations into the K expression and solve: = 3.39 × 10 −4 M ( 6.61 × 10 −4 M) ( 6.61 × 10 −4 M) = 776.
