What is the difference between a complete ionic equation and net ionic equation?
In the complete ionic equation, soluble ionic compounds and strong acids are rewritten as dissociated ions. In the net ionic equation, any ions that do not participate in the reaction (called spectator ions) are excluded.
What is a complete ionic equation?
The complete ionic equation indicates all of the dissociated ions in a chemical reaction. The net ionic equation cancels out ions that appear on both sides of the reaction arrow because they essentially don't participate in the reaction of interest. The ions that are canceled out are called spectator ions.
What is the difference between molecular complete ionic and net ionic equation in which circumstances would the complete and net ionic equation of a reaction is identical?
Net ionic equation shows only the chemical species that are involved in a reaction. Complete ionic equation shows the chemical species that are involved in a reaction and the spectator ions. The complete and net ionic equations will be identical if there are no spectator ions.

Net ionic equations are equations that show only the soluble, strong electrolytes reacting (these are represented as ions) and omit the spectator ions, which go through the reaction unchanged.

What is the net ionic equation for silver chloride?
This net ionic equation tells us that solid silver chloride is produced from dissolved and ions, regardless of the source of these ions. In comparison, the complete ionic equation tells us about all of the ions present in solution during the reaction, and the molecular equation tells us about the ionic compounds that were used as the sources ...
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 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.
What is net ionic equation?
In the net ionic equation, any ions that do not participate in the reaction (called spectator ions) are excluded. As a result, the net ionic equation shows only the species that are actually involved in the chemical reaction. Created by Sal Khan. This is the currently selected item.
What are the neutral molecules in the molecular equation?
Transcript. In the molecular equation for a reaction, all of the reactants and products are represented as neutral molecules (even soluble ionic compounds and strong acids). In the complete ionic equation, soluble ionic compounds and strong acids are rewritten as dissociated ions.
Why doesn't NaNO3 bond?
Direct link to von luger's post “They don't bond together ...”. They don't bond together here because the compound NaNO3 is soluble in water. In net ionic equations, only the formation of the precipitate is shown, not the soluble compound. You can check if a substance is soluble in water by using a solubility chart.
Can you decompose NaCl?
No, we can't call it decomposition because that would suggest there has been a chemical change. If you dissolve crystals of NaCl in water, you get a solution of Na+ and Cl- ions, but if you evaporate the water you get back your crystals of NaCl - overall, you've gone through a cycle and nothing has changed.
Why is there no net ionic equation?
There is no net ionic equation because there is no reaction (all fours ions are exactly the same on each side, all of them are stricken out as being spectator ions). Often NR is used to signify no reaction. You will find additional NR examples at 13, 23, 28, and 44 in my problem sets. There are several examples at #44.
What are ionic compounds?
Ionic compounds are between metals and nonmetals or between metals and polyatomic ions. Examples are sodium chloride (NaCl), magnesium nitrate [Mg (NO 3) 2] and ammonium sulfate [ (NH 4) 2 SO 4 ]. When an ionic substance is dissolved in aqueous solution, it ALWAYS ionizes and the ions always have a charge.
What is the reaction between sodium sulfate and barium chloride?
Here are two examples: barium chloride solution reacts with sodium sulfate solution to make solid barium sulfate and aqueous sodium chloride. aqueous solutions of hydrochloric acid and sodium hydroxide react to produce sodium chloride and water. The wording in problems like the above can vary somewhat.
Which ion is the spectator ion?
In both of the example equations above, the sodium ion and the chloride ion are the spectator ions. Here's why identifying the spectator ions is important: to go from a complete ionic equation to a net ionic equation, all spectator ions are eliminated from the equation.
Do molecules ionize in solution?
Molecular substances never ionize in solution, they exist as complete molecules and they NEVER have a charge. By the way, molecular compounds are also called covalent compounds. All the bonds in molecules like the examples above are covalent. Not one ionic bond exists in a covalent compound.
Can you use words for ionic equations?
Only full formulas (never words or ions) are involved in a complete molecular equation. Ions (never words) will be used for the complete ionic equation and the net ionic equation, which will follow just below. You can use words for an ionic equation (either complete or net), it just isn't usually done.
What is an ionic equation?

What are the two most common forms of ionic equations?
The two most common forms of ionic equations are complete ionic equations and net ionic equations. The complete ionic equation indicates all of the dissociated ions in a chemical reaction. The net ionic equation cancels out ions that appear on both sides of the reaction arrow because they essentially don't participate in the reaction of interest.
How are ions stabilized in aqueous solutions?
The ions in aqueous solutions are stabilized by ion-dipole interactions with water molecules. However, an ionic equation may be written for any electrolyte that dissociates and reacts in a polar solvent. In a balanced ionic equation, the number and type of atoms are the same on both sides of the reaction arrow.
Why are strong acids written as ions?
Strong acids, strong bases, and soluble ionic compounds (usually salts) exist as dissociated ions in aqueous solution, so they are written as ions in the ionic equation. Weak acids and bases and insoluble salts are usually written using their molecular formulas because only a small amount of them dissociates into ions.
