Question

Volume of 3%solution of sodium carbonate necessary to neutralise a litre of 0.1 N sulphuric acid is

• A. 176.66 ml
• B. 156.6 ml
• C. 116.0 ml
• D. 196.1 ml

Hint:

Use the equivalence factor and the molarity of the acid and base to calculate the volume needed for neutralization.

Answer 1

The Correct Option is A

Step 1: Use the neutralization equation.
The neutralization of sulfuric acid and sodium carbonate can be represented by \( \text{H}_2 \text{SO}_4 + \text{Na}_2 \text{CO}_3 \rightarrow \text{Na}_2 \text{SO}_4 + \text{CO}_2 + \text{H}_2 \text{O} \).
Step 2: Conclusion.
The required volume is 176.66 ml based on the equivalent amounts of acid and base. Final Answer: \[ \boxed{176.66 \, \text{ml}} \]
