Direction for: In each of the following questions a statement of Assertion is given followed by a corresponding statement of Reason just below it. Of the statements mark the correct answer as
Assertion: \[1.575g{{H}_{2}}{{C}_{2}}{{O}_{4}}.2{{H}_{2}}O\] in 250 Ml solution makes it 0.1 N. Reason: \[{{H}_{2}}{{C}_{2}}{{O}_{4}}.2{{H}_{2}}O\] is a dihydrate organic acid.A) If both Assertion: and Reason: are true and the Reason: is the correct explanation of the Assertion:
B) If both Assertion: and Reason: are true but the Reason: is not the correct explanation of the Assertion:
C) If Assertion: is true but Reason: is false
D) If both Assertion: and Reason: are false
Correct Answer: B
Solution :
\[{{K}_{4}}[Fe{{(CN)}_{6}}],\] \[F{{e}^{2+}}\] [\[F{{e}^{2+}}=[Ar]3{{d}^{6}},4{{s}^{0}}\] E of \[[Fe{{({{H}_{2}}O)}_{6}}]C{{l}_{3}},Fe\] \[F{{e}^{3+}}\] \[F{{e}^{3+}}=[Ar]3{{d}^{5}},4{{s}^{0}}\] is an organic acid which contains 2 molecules of water of crystallisation.
