Other names for a double replacement reaction are a double displacement reaction, exchange reaction, or salt metathesis reaction. A double replacement reaction is called a double decomposition reaction, but the term is reserved for when one or both of the reactants doesn’t dissolve in a solvent.
An example of a double replacement reaction is the reaction between silver nitrate and sodium chloride in water. Both silver nitrate and sodium chloride are ionic compounds. Both reactants dissolve into their ions in aqueous solution. The silver ion picks up the sodium’s chloride ion to form silver chloride, while the sodium ion picks up the nitrat...
You can recognize a double replacement reaction in a chemical equation by checking whether the cations exchange anions with each other. If the states of matter of the reactants and products are listed, look for a reaction between two aqueous solutions that yields one aqueous product (aq) and one that precipitates to form a solid product (s). If you...
There are several categories of double replacement reactions, including neutralization, alkylation, acid-carbonate reactions, counter-ion exchange, aqueous metathesis with precipitation (precipitation reactions), and aqueous metathesis with double decomposition (double decomposition reactions). However, the two types most often seen in general chem...

Here is an example of a double replacement reaction: BaCl 2 ( a q) + Na 2 SO 4 ( a q) → Ba SO 4 ( s) + 2 Na Cl ( a q) In this example, the cations are Ba 2 + and Na + , and the anions are Cl − and SO 4 2 − . If we swap the anions, or cations, we get as our products BaSO 4 and NaCl . Don't forget stoichiometry!
Double replacement reaction occurs when the cations and anions of two ionic compounds are exchanged. The figure below clearly illustrates how this swap takes place. When the chemical formula for each ionic compounds is written correctly, you can balance the equation like any other chemical equations by making sure the number of atoms for each element is the same on the left and the right.
Aug 19, 2020 · In a double-replacement reaction, what type of compounds are usually the reactants? A double-replacement reaction occurs between sodium sulfide and hydrogen chloride. Write the rest of the chemical equation and balance it. Na 2 S + HCl →; In double-replacement reaction, one of three possible types of products usually form. What are the three ...
During double replacement, the cations and anions of two different compounds switch places. Written using generic symbols, it is: AB + XY ---> AY + XB. A and X are the cations (postively-charged ions) in this example, with B and Y being the anions (negatively-charged ions).
