Question

A(n) _________________________________ reaction is one where the cations of two ionic compounds switch places. An example of this is when sodium chloride reacts with silver nitrate to form silver chloride and sodium nitrate.

a) Double displacement
b) Combustion
c) Single displacement
d) Acid-base

Answer 1

A reaction where the cations of two ionic compounds switch places is called a double-replacement reaction, represented by the general equation AB + CD → AD + BC.

Step-by-step explanation:

The type of reaction where the cations of two ionic compounds switch places is known as a double-replacement reaction. In this process, the cations and anions from two different reactants swap partners to form two new compounds, one of which is often a solid precipitate, a gas, or a molecular compound like water. The general equation for this type of reaction is represented as AB + CD → AD + BC. A real-world example of a double-replacement reaction is the reaction between sodium chloride (NaCl) and silver nitrate (AgNO₃), which produces silver chloride (AgCl) and sodium nitrate (NaNO₃).
