Explain double displacement in chemistry

1.	Explain double displacement in chemistry
Answer» A reaction involving the exchange of ions between the reactants is termed as Double displacement reaction.Consider the following double displacement reaction.\tChemical reaction between Na2S and HCl.\tNa2S + HCl\xa0→ NaCl + H2S\xa0 The Exchage of ion between the two reactants to forms new product is called double displacement reaction.Na2So4 + BaCl2 + 2NaCl Just changing of element to other compound. for eg-: BA CL 2 + n a 2 s o 4 is equal to P A S o4 + 2 NACL
