Chapter 3, Problem 97SCQ

(a)

Interpretation Introduction

Interpretation:

Preparation of ${\text{BaSO}}_{\text{4}}$ by precipitation reaction by using given materials and the complete balanced equations for the reaction chosen should be written,

Concept introduction:

Precipitation reaction: The formation of the product is insoluble when the ions combine in the solution is called precipitation reaction.

Acid - base reaction: Formation of the salt from the cation from the base and anion from the acid and formation of water is also the product.

Gas forming reaction: The reaction of acid and metal carbonates which produce carbonic acid. The carbonic acid decomposes which gives water and carbon dioxide.

Oxidation - reduction reaction: The electrons are transferred to one to other is called oxidation reduction reaction.
