Statement 1: When 20 ml of 0.1 M - solution is treated with excess of solution, the liberated exactly requires 20 ml of 0.3 M - solution for titration.
Statement 2: For solution, molarity and normality are equal, while for solution, normality is six times the molarity.
Options:
Answer:
D
Solution:
20 ml 0.1 M = 2 mmol = 12 meq, so the liberated is 12 meq and needs 12 mmol of ( = 1) = 20 ml of 0.6 M, not 0.3 M - I is incorrect. II is correct: thiosulphate has = 1 (M = N), while dichromate in acid has = 6 (N = 6M). Hence (d).
