Net Ionic Equations
When writing net ionic equations, how do you know which molecules will be written as ions and which molecule(s) will be written together (not as ions)?

Re: Net Ionic Equations
Do you have a specific example or a specific problem you are stuck on? I'm not quite sure how to answer your question broadly...

I believe that you would have to know the solubility rules. If something is soluble, then it shows up as ions. If the solubility rules says that a molecule or compound is not soluble, then the molecule or compound is written together and not dissociated into ions.

For example, in 17b) under Fundamentals J, it asks to write the chemical reaction for when KClO reacts with H2O. The reaction looks like...
ClO- + H2O --> HClO + OH-
In this example, why are H2O and HClO not written as ions?
ClO- + H2O --> HClO + OH-
In this example, why are H2O and HClO not written as ions?

Re: Net Ionic Equations
There are solubility rules that help you identify which ones will dissociate in water and become aqueous, and those that will not. The best way to know is just to memorize the solubility rules. It was mandatory in HS AP Chem to know them, but I'm not sure if Lavelle will have us memorize them too.

Re: Net Ionic Equations
If it can dissolve into ions, you must represent it as ions (so covalent molecules stay how they are) and it is net it must be simplified to show only the ions that change in a reaction.
