Question

Statement 1: Isomorphous substances form crystals of same shape and can grow in saturated solution of each other.
Statement 2 : They have similar constitution and chemical formulae.

• A. If both Statement $1$ and Statement $2$ are true and the statement $2$ is the correct explanation of the statement $1$
• B. If both Statement $1$ and Statement $2$ are true but statement $2$ is not the correct explanation of the statement $1$
• C. If Statement $1$ is true but Statement $2$ is false
• D. If Statement $1$ is false but Statement $2$ is true

Answer 1

Answer: (A)

Example of isomorphous compounds are $K_2SO_3, K_2CrO_4$,
$K_2SeO_4$ (valency of $S, Cr, Se = 6$) and $ZnSO_4 \cdot 7H_2O$,
$MgSO_4 \cdot 7H_2O, FeSO_4 \cdot 7H_2O$ (valency of $Zn, Mg, Fe =2$)
