Which of the following pairs of compounds is isomorphous?
- A \(\mathrm{NaCl}, \mathrm{KCl}\)
- B \(\mathrm{NaF}, \mathrm{NaNO}_3\)
- C \(\mathrm{CaCl}_2, \mathrm{NaNO}_3\)
- D \(\mathrm{CaCO}_3, \mathrm{NaNO}_3\)
Answer & Solution
Correct Answer
(D) \(\mathrm{CaCO}_3, \mathrm{NaNO}_3\)
Step-by-step Solution
Detailed explanation
Two or more substances having the same crystal structure called isomorphous.
They shows the same atomic ratio (Iso- Same, Morphous Form). Eg- NaF and MgO (1:1), NaNO3 and \(\mathrm{CaCO} 3\) (1:1:3) \(\mathrm{NaCl}\) and \(\mathrm{KCl}\) have almost all the properties identical but the crystal structures are different.
