Question

Lead Sulphate + Ammonium Hydroxide $\to$ Lead hydroxide + Ammonium Sulphate

The reaction is an example of:

• A. Single displacement reaction
• B. Double decomposition reaction
• C. Combination reaction
• D. Decomposition reaction

Answer 1

The correct option is B Double decomposition reaction

A double decomposition reaction is a reaction in which the positive ions and negative ions in two compounds switch partners to form two new compounds.

The older term double decomposition has been largely replaced by the terms double displacement, double replacement, and metathesis.

Hence, the correct option is $\text{B}$
