Double Displacement Reactions Study Guide
Complete the following study guide as you watch the Double Displacement Reactions
Video OR read page 184 in your textbook.
A double displacement reaction occurs when two ionic compounds in aqueous
solution exchange ion partners: AC + BD  AD + BC
Usually one of the products becomes _______________(forms a solid precipitate). The
other product stays _______________(dissolved in water). If both products are soluble,
then essentially there is no reaction and all ions stay dissolved. Use the
_____________________ to help you! This only applies to the products in a double
displacement reaction…
Notice that the positive ions always combine with the negative ions! A+ combines with Dand B+ combines with C-.
Don’t forget to check ion charges when you write new formulas!
Examples:
Silver nitrate reacts with sodium chloride to form silver chloride and sodium nitrate:
Lead (II) nitrate reacts with sodium iodide to form:
Predict the products:
CaCl2 + NaOH 
Are the products soluble in water?
