📍 Ensure all concentrations are in Molarity (mol/L) before plugging them into equilibrium expressions. How to Use Answer Keys Effectively
The substance with the lower required concentration of the precipitating agent will fall out of solution first. Common Pitfall: Don't just look at the Kspcap K sub s p end-sub
