Net Ionic Equations

Postby Caitlin_Murphy_3C » Sun Dec 02, 2018 9:13 pm

Will we need to know how to write net ionic equations for the final? How do you know the charge for each ion when finding the net ionic equation?

I think net ionics are useful for identifying bronsted acids and bases in a chemical reaction. You can usually identify the charge on the icon by the oxidation state.

For metals and nonmetals (in Group 1, Group 2, and Groups 13-18), you can determine an ion's charge by looking at the valence electrons in the s and p group. Calcium for example would be a +2 charge. Sulfur would have a -2 charge because it has 6 valence electrons and needs two more to complete its octet. Transition metals can vary but its total net charge can be determined by looking at the net charge of whole molecule. For example, if the net charge of the molecule is -2 then Iron in Fe2O3 would have a +2 charge.
