Question

Aqueous solution of Sodium Sulphate and barium chloride react as follows:
$N{a_2}S{O_4} + BaC{l_2} \to 2NaCl + BaS{O_4}$
A. Identify the type of reaction
B. Define the type of reaction
C. Suggest other name to this reaction

Answer 1

Hint: In order to answer this question we can refer to the reaction given above which clearly tells us that the reactants will dissociate into ions and then the ions of the metals will be exchanged. By this you may simply guess the name of the reaction. And if you will observe more deeply then you will catch that the ions which are getting exchanged are of equal charges, and now you can simply define the type of reaction. Lastly based on your knowledge suggest another suitable name for this reaction.

Complete answer:
Step 1: In the given reaction by comparing the reactants and the products we will find that the reactants have exchanged their ions in their product side. Thus we can easily conclude that the reaction is “ion-exchange reaction”.
Step 2: In the given reaction by comparing the reactants and the products we will find that the charge of the ions which are getting interchanged is equal. Thus we can conclude that this is a type of ion-exchange reaction in which equal charges are getting interchanged.
Step 3: We know that if in any reaction one element takes the place of another element in the compound that reaction is known as displacement reaction whose concept perfectly suits this reaction. And hence another name for this reaction will be Displacement Reaction.
So, the required answers are:
A. Identify the type of reaction: Ion-exchange Reaction
B. Define the type of reaction: A type of ion-exchange reaction in which equal charges are getting interchanged.
C. Another name: Displacement Reaction

Note: Ion-exchange reaction is a type of chemical reaction between two substances (each consisting of positively and negatively charged species called ions) that involves an exchange of one or more ionic components.
