Chapter 9, Problem 7STP

Interpretation Introduction

Interpretation: The reaction needs to be explained when ${\text{AgClO}}_{\text{3}}\left(\text{aq}\right)$ and ${\text{NaNO}}_{\text{3}}\left(\text{aq}\right)$ are mixed.

Concept introduction:

The precipitation reaction is the double displacement reaction which occurs when reaction between two aqueous solutions containing ions takes place, in which reaction of ions may takes place and a compound insoluble in solvent is formed.

Answer to Problem 7STP

Option A is correct.

Explanation of Solution

Reason for correct option:

When ${\text{AgClO}}_{\text{3}}\left(\text{aq}\right)$ and ${\text{NaNO}}_{\text{3}}\left(\text{aq}\right)$ combined the following reaction is take place:

${\text{AgClO}}_3\left(\text{aq}\right){\text{+NaNO}}_3\left(\text{aq}\right)\to {\text{AgNO}}_{\text{3}}\left(\text{aq}\right){\text{+NaClO}}_3\left(\text{aq}\right)$

Both the product formation is aqueous state. Therefore, there is no possibility for visible reaction.

Conclusion

Reason for incorrect option:

Option B, C and D are incorrect because the reaction is not occurring. And both the product formed is soluble in water.
