7.9 DOUBLE REPLACEMENT REACTIONS
Double The Excitement
When two ionic compound solutions are mixed…
Either a homogeneous mixture will occur
Or a Double Replacement chemical reaction will occur
Double Replacement Reactions: An exchange of positive ions between two compounds
How to Create Formulas
Examples:
• AB+CD – AD+CB
• AE+TG – AG+TE

Equation!
AB + XY AY + XB 1) The outside portions (cation A and anion Y) combine to make a formula called AY. 2) the inside portions (anion B and cation X) switch so X (positive charge) and B (negative charge) goes secind to make a formula called XB.
