Mercury (II) nitrate solution reacts with potassium iodide solution to give a yellow precipitate of Mercury (II) while potassium nitrate remains in solution. The balanced chemical equation for this reaction is shown below:
Hg(NO3)2 (aq.) + 2KI (aq.) = HgI2 (s) + 2KNO3 (aq.)
This is an example of a double displacement reaction where two compounds exchange cations and anions with one another. This may also be grouped under the category of precipitation reactions as a solid is being precipitated (and separated) from solution. This is a classic example where one reaction fits into more than one category.
