Question

Explain and give equations for :
(i) displacement reaction
(iii) neutralisation
(ii) double displacement reaction​

Answer 1

Answer:

A displacement reaction is the one wherein the atom or a set of atoms is

Answer 2

Explanation:

(i) Displacement reaction is a chemical reaction in which a more reactive element displaces a less reactive element from its compound. Both metals and non-metals take part in displacement reactions. Example : Reaction of iron nails with copper sulphate solution.

• 2KI + Cl2 → 2KCl + I2

(ii) A neutralization reaction can be defined as a chemical reaction in which an acid and base quantitatively react together to form a salt and water as products. In a neutralization reaction, there is a combination of H+ ions and OH– ions which form water.

• NaOH+HCl⟶NaCl+H2O

(iii) A double displacement reaction is a type of reaction in which two reactants react and the positively charged ions of one and the negatively charged ion of the other reactant are interchanged.

An example of this type of reaction is the reaction of copper sulphate and iron.

• CuCl 2(aq) + 2 AgNO 3(aq) → Cu(NO 3) 2(aq) + 2 AgCl(s)
