Introduction to Net Ionic Equation
In chemistry, we depend upon chemical equations to study the behavior of different elements and the mechanism of a chemical reaction. We can write these chemical equations in many ways based on our goals.
How to Write Net Ionic Equations?
To write a net ionic equation, you first have to balancing ionic equations and then determine whether the reacting substances form ions or react by giving solid precipitates. It helps to predict the nature of reacting compounds (either ionic or molecular), analyzing strong bases and acids, and predict the solubility ratio of compounds.
How to Write a Net Ionic Equation
First of all, check whether the given equation is balanced or not. If not, then balancing ionic equations using the chemical equation balancer on the home page by using the periodic table. You can also get detailed results with this chemical equation balancer.
Net Ionic Equation Example
Suppose you have been writing net ionic equations for a reaction between silver nitrate and sodium chloride. First of all, you need to write the balanced chemical equation of this reaction which would be such as
Bottom Line
Don't forget that we cannot write a net ionic equation for a chemical reaction where all the products are aqueous. In such situations, all the aqueous ions will cancel out with each other, and no ion will be left behind.
What is the meaning of ionic equation?
Vocabulary. Complete ionic equation: a molecular equation that separates the molecules into their ion forms. Net ionic equation: a molecular equation that depicts the ions or molecules that experience a change within a reaction. Spectator ion: ions in a reaction that do not undergo any change.
What are spectator ions?
When looking at the complete ionic equation, the spectator ions will have the same charge and state of matter in the reactants and products. In this reaction, the sodium ion and the nitrate ion do not change. As a result, these are considered spectator ions.
Can a compound be separated into ion form?
This means that we separate each molecule into its ion form. (Note that only aqueous compounds can be separated.) If the compound is a solid or liquid, it must stay in its molecule form. The complete ionic equation for the reaction above would be as follows: Finally, we can use the complete ionic equation to write the net ionic equation.
What is the ionic compound that precipitates out of solution?

What compound will dissociate completely in aqueous solution?
In your case, sodium hydroxide, NaOH, and copper (II) nitrate, Cu(NO3)2, will dissociate completely in aqueous solution to form cations and anions. The reaction will produce copper (II) hydroxide, Cu(OH)2, an insoluble ionic compound that precipitates out of solution, and aqueous sodium nitrate, NaNO3, another soluble ionic compound.

How does sodium interact with water?
Each chloride ion is interacting with multiple water molecules through the positive dipole of the water, and each sodium ion is interacting with water molecules through the negative dipole of the water.
What happens when ions are involved in a reaction?
When ions are involved in a reaction, the equation for the reaction can be written with various levels of detail. Depending on which part of the reaction you are interested in, ...
What are ionic species that remain unchanged during a reaction called?
Ionic species that remain unchanged like this during a reaction are called spectator ions. Since spectator ions appear on both sides of the equation, we can cancel them out, similar to how we can cancel out equal terms on either side of a math equation:
What is a balanced equation?
A molecular equation is sometimes simply called a balanced equation. In a molecular equation, any ionic compounds or acids are represented as neutral compounds using their chemical formulas. The state of each substance is indicated in parentheses after the formula.
