Sodium chloride is not purified by sublimation.
No, because neither of them sublimate at 760 torr (1 atm). They melt. You could separate them by melting point, as NaCl has a melting point of 801ºC, but KCl has a melting point of 770ºC.
NaNO3(ac) + KCl(ac)-----> NaCl(ac) + KNO3(ac)

Salt (sodium chloride, NaCl) substitutes are potassium chloride (KCl) or mixtures NaCl + KCl.
The molar mass of NaCl is 58.44 g/mol The molar mass of KCl is 74.5513 g/mol This is because the Potassium atom (K) is heavier than the Sodium atom (Na). Thus one gram of NaCl will contain more molecules (formula units) than one gram of KCl.
To decrease melting point of NaCl
HCl, NaCl, KCl
NaCl, KCl
NaNO2 and KCl
As the size of Na is smaller than the size of K,NaCl will have stronger bond than KCl
Yes, iodine and naphthalene can be separated by sublimation because they have different sublimation points. Iodine sublimes at a lower temperature compared to naphthalene, allowing for the selective separation of the two substances based on their sublimation properties.
