200 cc of \( x \times 10^{-3} M \) potassium dichromate is required to oxidise 750 cc of 0.6 M Mohr's salt solution in acidic medium. Here x =
- A 125
- B 250
- C 375
- D 500
Answer & Solution
Correct Answer
(C) 375
Step-by-step Solution
Detailed explanation
\(M_1 V_1 n_1 = M_2 V_2 n_2\) \(0.6 \times 750 \times 1 = x \times 10^{-3} \times 200 \times 6\) \(450 = x \times 1.2\) \(x = \frac{450}{1.2}\) \(x = 375\)
