Question

Assertion: Isomorphous substances from crystals of same shape and can grow in saturated solution of each other.
Reason: They have similar constitution and chemical formulae.
A. (a)If both assertion and reason are true and the reason is the correct explanation of the assertion.
B. (b)If both assertion and reason are true and the reason is not the correct explanation of the assertion.
C. (c )If the assertion is true but reason is false.
D. (d)If assertion is false but reason is true.

Answer 1

Correct Answer - a
Example of isomorphous compounds are `K_(2)SO_(3), K_(2)CrO_(4), K_(2)SeO_(4) ("valency of " S, Cr, Se = 6) and ZnSO_(4) dot 7H_(2)O, MgSO_(4)dot 7H_(2)O, FeSO_(4)dot 7H_(2)O` ( valency of `Zn, Mg, Fe=2`).
