• Involves the exchange of partners in the reaction

• The reaction involves two ionic compounds as reactants.
• As the equation above shows, the ions “change partners” to form the products.
• This type of reaction commonly occurs in aqueous solutions.

How much is too much?
• We can take advantage of the individual solubilities of different substances in water. – If the product of a reaction is very soluble, it
will stay in solution (aq).– If the product is only slightly soluble,
(insoluble), it is likely that more will be produced than can dissolve

Types of Double Displacement
Reactions• There are three types of double displacement reactions:
1) Precipitation Reaction2) Reactions Producing a Gas3) Neutralization Reactions

Sample Problem #1(Precipitation Rxn)
• Write a balanced equation to represent the reaction of an aqueous solution of barium chloride with an aqueous solution of ammonium sulfate. Indicate the physical state of the reactants and products involved.

Neutralization Reactions
• Special type of double displacement reaction
• Three types:

1. Neutralization Reactions
With a hydroxide compound• General equation:
Acid + Base --> Salt + Water
• Ex: HCl (aq)+ NaOH (aq) --> NaCl (aq) + H2O (l)
![Page 9: CCBAB Compound ABCompound CD AD Compound ADCompound CB D ++ Magnesium Chloride MgCl 2 Calcium Hydroxide Ca(OH) 2 Magnesium Hydroxide Mg(OH) 2 Calcium Chloride.](https://reader036.fdocuments.in/reader036/viewer/2022062517/56649f2e5503460f94c484f0/html5/thumbnails/9.jpg)
Sample Problem #3
(Neutralization Reaction)• Write the balanced chemical equation for the neutralization reaction of sodium hydroxide with hydrochloric acid
![Page 10: CCBAB Compound ABCompound CD AD Compound ADCompound CB D ++ Magnesium Chloride MgCl 2 Calcium Hydroxide Ca(OH) 2 Magnesium Hydroxide Mg(OH) 2 Calcium Chloride.](https://reader036.fdocuments.in/reader036/viewer/2022062517/56649f2e5503460f94c484f0/html5/thumbnails/10.jpg)
2. Neutralization Reactions
With a carbonate compound• General Equation Acid + carbonate compound --> water + carbon dioxide + ionic compound
• H2SO4(aq) + CaCO3(s) --> H2O(l) + CO2(g) + CaSO4 (s)

3. Neutralization Reactions
With a sulphite compound• General Equation Acid + sulphite compound --> water + sulphur dioxide + ionic compound
• 2H3PO4(aq) + 3CaSO3(s) --> 3H2O(l) + 3SO2(g) + Ca3(PO4)2 (s)
