Favorite Double Displacement Reactions

It covers three types.

Double displacement reactions. All of the examples on this page are double displacment reactions. Completing Double Displacement Reactions The products of a DD reaction are the result of the ions trading partners. A double displacement reaction is a type of chemical reaction in which the reactant ions exchange places to form new products.

1191 AB CD AD CB In this reaction A and C are positively-charged cations while B and D are negatively-charged anions. Generally it can be represented as follows AB CD. Two reactants yield two products.

Na 2 CO 3 2 HCl 2 NaCl H 2 CO 3 Bubbles of a colorless gas are evolved when these solutions are mixed. For example on mixing a solution of barium chloride with sodium sulphate a white precipitate of barium sulphate is immediately formed. During this reaction the cations and anions of two different compounds switch places forming two entirely different compounds.

The double displacement reaction is a pretty obvious extension of single displacement. Khan Academy is a 501c3 nonprofit organization. Mixed the equation for the hypothetical double displacement reaction is.

This ScienceStruck post explains the concept of double displacement reaction in chemistry along with a few examples. Double displacement reactions generally take place in aqueous solutions in which the ions precipitate and there is an exchange of ions. A characteristic of a double-replacement equation is that there are two compounds as reactants and two different compounds as products.

Those reactions in which two compounds react by an exchange of ions to form two new compounds are called double displacement reactions. Double Displacement Reaction In a double replacement reaction parts of two compounds switch places to form two new compounds. But carbonic acid H 2 CO 3.
