sodium bromide melting point
The melting point of an element or compound is the highest temperature at which it will melt, if heated to a certain temperature. The melting point of a substance depends on its physical properties and chemical bonding, which is why some substances have low melting points while others have high ones.
Sodium on its own has metallic bonding, which involves an electrostatic force of attraction between the positive ions of Sodium and the negative delocalized electrons circulating around the ions. In contrast, Sodium Bromide has ionic bonding, which is a stronger type of bonding, which involves an electrostatic force between the positive ions of Sodium and their corresponding negative Bromide ions.
It has a higher melting point than Sodium on its own because of the ionic bonding between its atoms. The reason for this is because ionic bonding between Sodium and Bromide requires more energy (and therefore higher temperatures) than Sodium on its own does.
Sodium bromide is an inorganic compound with the chemical formula NaBr and has the same chemical structure as sodium chloride. It is a widely used source of the bromide ion, and has many applications. The crystalline solid is white and has a feebly bitter taste, easily soluble in water. It is also soluble in alcohol. Sodium bromide is used in the manufacture of liquid photographic film and as a sedative, and is a major brominating agent. It is available as crystals, granules, or powder and in a variety of grades.
