A reaction of a type: ​

$\text{AB}+\text{CD}\to \text{AD}+\text{CB}$, involves

• A. Combination of AB and CD
• B. Exchange of ions of AB and CD
• C. Decomposition of AB and CD
• D. No chemical change

Answer 1

The correct option is B Exchange of ions of AB and CD

$\text{AB}+\text{CD}\to \text{AD}+\text{CD}$
The given reaction represents a double displacement reaction. Such reaction involves the mutual exchange of ions.​

Therefore, option C is correct here.
