Which of the following samples is/are chemically equivalent to 40 mL of 0.25 N $K_{2} Cr_{2} O_{7}$ in acidic medium?

Answer:

A, B, C

Solution:

40 mL of 0.25 N $= 10$ meq.

(A) $100 \times 0.1 \times 1 = 10$ meq: equivalent.

(B) $25 \times 0.2 \times 2 = 10$ meq: equivalent.

(D) $FeC_{2} O_{4}$ has n-factor 3: $50 \times 0.1 \times 3 = 15$ meq: not equivalent.

Answer: A, B, C.
