Alright guys, I am a little bit confused on how to find the concentration of ions in a reaction. In a solution, it is relatively easy. Are the number of ions in the beginning the same they are in the end? Please give me some general guidelines: i know to begin with a balanced equation , then a net ioc equation...but how does the net ionic equation help me?? Thank you so much, I will further update this question...so I can't specifically put my questions into words! Any help appreciated, thank you so much.
