Give examples of following reactions Double decomposition

Explanation

### Step-by-Step Text Solution:

**Step 1: Understand the Concept of Double Decomposition Reaction**
A double decomposition reaction, also known as a double displacement or metathesis reaction, occurs when two compounds exchange ions to form two new compounds. The general form of this reaction can be represented as:
\[ AB + CD \rightarrow AD + CB \]
where \( A \) and \( C \) are cations (positively charged ions) and \( B \) and \( D \) are anions (negatively charged ions).
