What type of reaction is displayed below?
AgCl + KBr → KCl + AgBr
a
synthesis
b
decomposition
c
single replacement
d
double replacement
d
double replacement
The reaction shown below is a type of reaction known as double replacement. In a double replacement reaction, the positive and negative ions of two ionic compounds switch places and form two new compounds. In this case, AgCl and KBr exchange ions to form KCl and AgBr.
To determine the type of reaction displayed below, we need to analyze the chemical equation provided:
AgCl + KBr → KCl + AgBr
In this equation, we can see that the reactants AgCl and KBr exchange ions to form new compounds KCl and AgBr. When two compounds swap ions to form new compounds, it is called a double replacement reaction.
Therefore, the correct answer is option d: double replacement.
