Question

Jose and Sue were investigating the formation of precipitates in chemistry lab. They mixed a silver nitrate solution with a sodium chloride solution and immediately a white solid appeared in the bottom of the test tube. This white solid is a precipitate of silver chloride. The reaction is represented with the equation:
AgNO3(aq) + NaCl (aq) → AgCl (s) + NaNO3 (aq)
The equation represents a ________________ reaction.
A) synthesis
B) decomposition
C) neutralization
D) double replacement

Answer 1

In a double decomposition reaction, AgNo3 and NaCl combine to form NaNo3 and AgCl. The resulting AgCl precipitate is white as well. AgCl (silver chloride) with nitrate of sodium. It will be an insoluble solid, AgCl. The equation represents a double decomposition reaction. Therefore, option B is correct.

What is double decomposition reaction ?

A type of decomposition reaction known as a double decomposition reaction involves the exchange of positive and negative ions between two constituent reactants to create two new molecules.

When two compounds in a solution react to generate two new compounds through the exchange of radicals, this reaction is known as a double displacement reaction. Double decomposition reaction is another name for this kind of reaction.

Thus, option B is correct.
