Chapter 8, Problem 3STP

Interpretation Introduction

Interpretation :

The reaction that would result in the formation of solid must be chosen from the given list.

Concept Introduction :

A precipitation reaction is also known as double displacement reaction in which exchanges of ions between the two salts take place resulting the formation of an insoluble solid.

Answer to Problem 3STP

Correct answer: Option C is correct.

Explanation of Solution

Reason for correct option:Option C is correct because in precipitation reaction two soluble substances react to produce an insoluble solid or precipitate via double displacement reaction. In the reaction of Ba (NO₃)₂ and K₂SO_4, insoluble BaSO4 will be produced.

Conclusion

Reasons for incorrect options:Option A is incorrect as in the reaction of sodium chloride and potassium nitrate two soluble salts sodium nitrate and potassium chloride will be produced.

Option B is incorrect as there will be no reaction between silver nitrate and sodium nitrate.

Option D is incorrect as in the reaction of HCl and NaOH a soluble salt NaCl and water will be produced.
