Borax $+ H_2O \rightarrow A + B$. What are A and B respectively?
Show Hint
Borax hydrolysis produces a basic solution due to the strong base NaOH!
Updated On: Jun 6, 2026
- Strong base, Strong acid
- Strong base, Weak acid
- Weak base, strong acid
- Weak base, Weak acid
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Concept
Hydrolysis of Borax: $Na_2B_4O_7 + 7H_2O \rightarrow 2NaOH + 4H_3BO_3$.
Step 2: Meaning
$NaOH$ is a strong base. $H_3BO_3$ is a weak acid.
Step 3: Analysis
Borax yields NaOH (strong base) and Boric acid (weak acid).
Step 4: Conclusion
A is a strong base, B is a weak acid.
Final Answer: (B)
