Using Net Ionic Equation

Postby Jennifer Su 2L » Tue Jan 08, 2019 6:08 pm

Quoting the 6th edition textbook on page 427, it says "when a reaction involves fully dissociated ionic compounds in solution, the equilibrium constant should be written for the net ionic equation, by using the activity for each type of ion." I was wondering how you would know if there are ionic compounds that fully dissociates in the solution during a reaction. Is it by identifying ionic compounds in aqueous solutions on both sides of the molecular equation? In other words, if I see ionic compounds (aq) on both the reactant and product side of a molecular equation, should I automatically solve for a net ionic equation before I calculate K?

Yes, you have to get rid of spectator ions by writing a net ionic equation first. I'm assuming for this course we only need to identify simple ionic compounds, such as AgCl.
