Which of the following pairs of compounds is isomorphous?
Which of the following pairs of compounds is isomorphous?
$\mathrm{NaCl}, \mathrm{KCl}$
$\mathrm{NaF}, \mathrm{NaNO}_3$
$\mathrm{CaCl}_2, \mathrm{NaNO}_3$
$\mathrm{CaCO}_3, \mathrm{NaNO}_3$
Solution
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.
