7.9 DOUBLE REPLACEMENT REACTIONS

Double The Excitement

Page 2: Double The Excitement.  Either a homogeneous mixture will occur  Or a Double Replacement chemical reaction will occur  Double Replacement Reactions:

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.
