2 gm of metal carbonate is neutralized completely by \(100 \mathrm{ml}\) of \(0.1(\mathrm{~N}) \mathrm{HCl}\). The equivalent weight of metal carbonate is
- A 50
- B 100
- C 150
- D 200
Answer & Solution
Correct Answer
(D) 200
Step-by-step Solution
Detailed explanation
Hints: Number of gram equivalents of \(\mathrm{HCl}\) \(=\frac{100 \times 0.1}{1000}=0.01\) Number of gram equivalents of metal carbonate required for neutralisation must also be 0.01 . Thus, mass of 1 gram eqivalent of carbonate salt \(\frac{2}{0.01}=200 \mathrm{~g}\)…
