Type: MCQ-numerical-Hard-Class 11
What mass of 95% pure CaCO₃ will be required to neutralise 50 mL of 0.5 M HCl solution according to the following reaction?
CaCO₃ + 2HCl(aq) → CaCl₂(aq) + CO₂(g) + 2H₂O(l) [Calculate upto second place of decimal point]
A
3.65 g
B
9.50 g
C
1.25 g
D
1.32 g
Correct Answer
Option D
Detailed Explanation
The reaction requires 1 mole of CaCO₃ to neutralize 2 moles of HCl. The moles of HCl are 0.025, so 0.0125 moles of CaCO₃ are needed. This corresponds to 1.32 g of 95% pure CaCO₃.
