Experiment 8 Double Displacement Reactions All single displacement reactions have the general form A BC B AC 6 1 6 1 A B C B A C Here A A is an element and BC B C is usually an aqueous ionic compound or an acid consisting of B B and C C aqueous ions A displaces B B in BC B C resulting in the formation of a new element B B and a new ionic compound or
Double replacement reactions also called double displacement exchange or metathesis reactions occur when parts of two ionic compounds are exchanged making two new compounds The overall pattern of a double replacement reaction looks like this A B C D A D C B A double replacement reaction is a reaction in which the positive and negative ions of two ionic compounds exchange places to form two new compounds The general form of a double replacement also called double displacement reaction is ce AB ce CD rightarrow ce AD ce CB nonumber

Experiment 8 Double Displacement Reactions and NIE This lab explores double displacement reactions of aqueous solutions In this lab you will observe whether a reaction occurs and predict the products by mixing paired solutions together These results will be verified with the solubility table in the lab Table 1 Section 1 Purpose and Summary Carry out double displacement reactions involving different aqueous solutions Identify reactions that form precipitates evolve gases and increase temperature after mixing Predict whether a double displacement reaction will occur between two solutions
A double displacement reaction is a type of chemical reaction in which the reactant ions exchange places to form new products Usually a double displacement reaction results in precipitate formation The chemical bonds between the reactants may be either covalent or ionic Here are some suggestions First read the procedure carefully Make sure you have space to write your observations This is an OBSERVATION lab Observing Double Displacement Reactions Get a beaker for slops a 250 or 400 mL beaker should do nicely You are going to be working with cations of metals which cannot go down the sink
