## Total Ionic Equations
- First balance the equation and mark the ones that can be dissolved in water. $`(aq)`$. If the ones cannot be dissolved in water, mark them as solids and leave them.
- For all the ones that can be dissolved in water, break them down into their individual ions and write their charge, if there are multiple of an ion, put it as an coefficient. (meanning $`6Cl_2`$ becomes $`12Cl^-`$). This is called the `Ionic equation/Total ionci equation`
- For all the ones that can be dissolved in water, break them down into their individual ions and write their charge, if there are multiple of an ion, put it as an coefficient. (meanning $`6Cl_2`$ becomes $`12Cl^-`$). This is called the `Ionic equation/Total ionic equation`
- Remember, if you change the subscript or a charge of an element, that element becomes a new element.
- Cross out the same elements that are on both sides of the equation, remember, they must have the **same coefficient, charge, and be the same element** in order to cross out. This is called the `Net ionic equation`
- The elements you crossed out are the `spectator ions`, they do not participate in the reaction.
