An example of a precipitation reaction: Aqueous silver nitrate (AgNO3) is added to a solution containing potassium. Discover how ions are arranged in precipitation reactions and practise completing ionic equations using this lesson plan with activities for 1416 year. Regardless of physical state, the products of this reaction are \(Fe(OH)_3\) and \(NaNO_3\). There is no solid precipitate formed therefore, no precipitation reaction occurs.ġ. This particular example is important because all of the reactants and the products are aqueous, meaning they cancel out of the net ionic equation. Also the net ionic equation talked about in the problem is listed in the equations section above, but I repeat here. This form exists, to show which reactants and products are just floating in the solution, and which of them actually react. Cancel out all spectator ions (those that appear as ions on both sides of the equation.):Ĭo 2 - ( aq) 2Cl -( aq) 2Na ( aq) SO 4 2 -( aq) → Co 2 - ( aq) SO 4 2 -( aq) 2Na ( aq) 2Cl -( aq) 2AgNO 3 (aq) Na 2 S (aq) -> Ag 2 S (s) 2NaNO 3 (aq) But, that's not the end of precipitate equations - there's still one last step: turning it into a net ionic equation. Separate the species into their ionic forms, as they would exist in an aqueous solution. These equations can be used to represent what happens in precipitation reactions.
