Double+Replacement+IV

Station 1 A Double Replacement Reaction occurs when two compounds react with each other to form two new compounds.

1. Silver nitrate + Potassium chloride = Silver chloride + Potassium nitrate (AgNO3 + KCl = AgCl + KNO3) 2. Sodium chloride + Silver nitrate = Sodium nitrate + Silver chloride (NaCl + AgNO3 = NaNO3 + AgCl)

Representative Equation: Dennis & Denise go to prom togther, and Charlie & Cathy go together. At the end of the night, Dennis & Cathy leave together and Charlie & Denise leave together. Dennis&Denise + Charlie&Cathy = Dennis&Cathy + Charlie&Denise

Station 5 Barium Hydroxide + Sodium Sulfate --> Barium Sulfate + Sodium Hydroxide Ba(OH)2 + Na2SO4 --> BaSO4 + 2NaOH

This is a double replacement where two soluble salts make one unsoluble salt and one, new, soluble salt.
