Question

What type of salt is Pb(OH)NO$_3$?

• A. Common salt
• B. Mixed salt
• C. Acidic salt
• D. Basic salt

Hint:

Basic salts are often formed when incomplete neutralization occurs between a weak acid and strong base.

Answer 1

The Correct Option is D

Step 1: Understanding Salts:
Salts are classified into different categories depending on their composition:
Normal salt: Neutral salts formed by complete neutralization (e.g., NaCl).
Acidic salt: Formed when a strong acid and weak base react; contains replaceable H$^+$ (e.g., NaHSO$_4$).
Basic salt: Formed when a strong base and weak acid react; contains OH$^-$ ions (e.g., Pb(OH)NO$_3$).
Mixed salt: Contains two different cations/anions (e.g., CaOCl$_2$).
Step 2: Analysis:
Pb(OH)NO$_3$ contains hydroxyl (OH$^-$) groups along with nitrate ion (NO$_3^-$).
Presence of OH$^-$ means it is a basic salt.
Step 3: Final Answer:
Pb(OH)NO$_3$ is classified as a Basic salt.
