How to write a precipitation reaction equation

The reaction between these two solutes produces an insoluble yellow product. Reactions that result in the formation of an insoluble product are known as precipitation reactions. A precipitate is an insoluble solid formed by a reaction in solution.

How to write a precipitation reaction equation

Net Ionic Equation Most reactions in an aqueous medium involve ions. However, when a reaction takes place two kinds of ions usually emerge: The names imply the character of the ions with respect to the reaction.

Player ions are directly in the reaction whereas spectator ions fulfill the role of spectators and their primary function is keeping electrical neutrality in the solution. Consider the precipitation reaction that occurs when aqueous solutions of sodium chloride and silver nitrate are mixed.

A white precipitate of AgCl forms. The chemical equation for this reaction is written as: This equation contains all ions in the solution.

However, sometimes its necessary to only include those ions that are players and leave out the spectators. A chemical equation that contains only the player ions is called the net ionic equation nie. To get the nie 1 write out all soluble compounds as ions and 2 eliminate ions common to both reactants and products.

The resulting chemical equation is then the nie. For the equation above we have: The nie for this reaction is:Write an equation for the reaction that occurs when potassium hydroxide and nickel(II) bromide solutions are mixed.


Does a precipitation reaction occur? 2 KOH(aq)+NiBr?(aq)? When a precipitation reaction occurs, a chemical equation for the precipitation reaction that involves only the ionic species that react (the reactants) and the ionic compound that forms the precipitate (the products) is known as a net ionic equation.

Another way to write a precipitation reaction is as a net ionic equation. In the net ionic equation, the ions that don't participate in the precipitation are omitted. These ions are called spectator ions because they seem to sit back and watch the reaction without taking part in it.
