How is the melting point of an impure compound expected to change with recrystallization?
The melting point of an impure compound is expected to decrease with recrystallization. This is because impurities disrupt the crystal lattice structure, causing a broader melting point range. Recrystallization removes impurities, resulting in a purer compound with a higher melting point.
Would the melting point of caesium be higher or lower then sodium?
The melting point of cesium is lower than that of sodium. Cesium has a melting point of 28.4°C, while sodium has a melting point of 97.8°C.
Does sodium have a higher melting point then potassium?
Yes, sodium has a higher melting point than potassium. Sodium has a melting point of 97.8°C while potassium's melting point is much lower at 63.38°C.
Which has a higher melting point Neon or Argon?
Argon has a higher melting point than Neon. Neon melts at -248.6 degrees Celsius, whereas Argon melts at -189.4 degrees Celsius.
What would melt first germanium with a melting point of 1210 K or gold with a melting point of 1064 C?
1210 K is 937 C, so the germanium would melt first.
Higher melting point than expected?
It is indeed possible for a substance to have a higher melting point than expected. This normally happens when the substance is impure.

Would metals or non metals tend to have a higher melting point?
Tungsten has the highest melting point of the elements and it is a metal.
What happens if boiling point is higher than melting point?
The boiling point is always higher than the melting point.
Would the melting point of caesium be higher or lower then sodium?
The melting point of cesium is lower than that of sodium. Cesium has a melting point of 28.4°C, while sodium has a melting point of 97.8°C.
What must the melting point of the mold be compared to the temperature at which glass gets soft and why?
The melting point of the mold must be higher than the melting point of glass, or else it would not be able to hold the soft glass in the correct shape.
What element has the highest melting point out of lithium or magnesium?
Magnesium has a higher melting point.
Is the melting point of Xenon higher than the melting point of Helium?
Yes
Does rubidium have a higher melting point than potassium?
Yes, rubidium has a higher melting point than potassium. Rubidium has a melting point of 39.3°C, while potassium has a melting point of 63.4°C.
Does sodium have a higher melting point then potassium?
Yes, sodium has a higher melting point than potassium. Sodium has a melting point of 97.8°C while potassium's melting point is much lower at 63.38°C.
Which would you expect to have a higher melting point sodium chloride NaCI or aluminum oxide AI203?
The melting point of sodium chloride is 801 0C. The melting point of aluminium oxide is 2 072 0C.
Is the melting point of bromine higher or lower than the melting point of chlorine?
The melting point of bromine is -7,2 0C. The melting point of chlorine is -101,5 0C.
