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 $K_{2}S{O}_3,K_{2}Cr{O}_4$,
$K_{2}Se{O}_4$ (valency of $S,Cr,Se=6$) and $ZnS{O}_4\cdot 7H_{2}O$,
$MgS{O}_4\cdot 7H_{2}O,FeS{O}_4\cdot 7H_{2}O$ (valency of $Zn,Mg,Fe=2$)
