Explanation:
How is the relatively high melting point of sodium chloride related to its structure at the atomic scale? Observe sodium chloride crystals with a hand lens. Use your observations and the model of sodium chloride to support your claim.
Unlike the raltively low melting point of water (100 °C), NaCl has a much higher melting point (801 °C),.
Theater molecules in ice are held together by hydrogen bonds, which are relatively weak.
The ions in NaCl are held together by ionic bonds, whose electrostatic ,force is much greater.
The crystal structure makes the force even greater.
imagine a chloride ionin a NaCl crystal.
It has Na ions in front, behind, to the left, to the right, above and below.
Likewise the Na ion has Cl ions in front, behind, to the left, to the right, above and below.
It takes a lot of energy to berak these bonds and temprature is a measure of energy.
if you try the experiment make certain you are undr a fune hood and wear protective loves and apron. 801 °C can seriously burn skin and clothing
The temperature at which the liquid and the solid of refined compounds and elements can occur stable and in equilibrium is called the melting point.
How are the structure and the melting point related?
- Water has a relatively lower melting point of 100 °C compared to [tex]\rm NaCl[/tex] at 801 °C which has a much higher melting point. The water molecules in ice are bonded jointly by somewhat weak hydrogen bonds.
- On the other hand, [tex]\rm NaCl[/tex] ions are bonded together by ionic bonds, that has a greater electrostatic force and its crystal structure produces the force to be even more prominent.
- When a sodium and chloride ion is imagined in the [tex]\rm NaCl[/tex] crystal the sodium ions are present above, below, left and right of the structure and the chloride ions are similarly placed in the crystal structure.
- This type of structure needs a lot of energy to break and hence the melting point of the salt is more compared to the water.
Therefore, the melting point is related to the structural organization of the atoms.
