The difference is minimal, only 7 0C; the melting and boiling points of materials are specific and different; and this is because the compostion and structure are not identical.
The boiling point of NaCl is 1 413 0C. The boiling point of potassium chloride is 1 420 0C.
The boiling point of sodium chloride (NaCl) is 801 oC.Sulfur dichloride (SCl2) is decomposed before boiling.
KCl is an ionic compound and glucose is a molecular compound. Ionic compounds have higher boiling points than molecular compounds.
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.
