what is meant by displacement and double displacement reaction explain with the help of an example
Answers
Explanation:
displacement reactions
The reaction in which the place of the ion of a less reactive element in a compound is taken by another more reactive element by formation of its own ions is called displacement reactions
cuso4+Fe gives feso4+cu
double displacement reactions
The reaction in which the ions in the reactants are exchange to form a precipitate are called double displacement reactions
Agno3+Nacl gives Agcl+Nano3
A displacement reaction is a type of reaction which replaces part of one reactant with another.
Explanation:
A displacement reaction is a type of reaction which replaces part of one reactant with another. A displacement reaction is also known as a metathesis or substitution reaction. Two types of displacement reaction they are:
1. single displacement reaction:
Single displacement reactions are reactions in which one reactant replaces one part of the other;
AB + C = AC + B
Example is the reaction between iron and copper sulfate to iron sulfate and copper:
Fe + CuSO₄ = FeSO₄ + Cu. One metal cation, bonding to the sulfate anion, takes the place of another.
2. double displacement reaction:
Double displacement reactions are reactions where the cations and anions in the reactants exchange partners to form products:
AB + CD → AD + CB
An example is the reaction between silver nitrate and sodium chloride to form silver chloride and sodium nitrate:
AgNO₃ + NaCl → AgCl + -1O₃
