The melting point is a temperature where given solid will melt. The melting point of salt is 801℃. Well, you all must be thinking “why does salt have a high melting point?”. Sodium chloride is a naturally occurring chemical compound with the formula NaCl. It consists of two different ions. The sodium (Na) is positively charged due to loss of an electron while the chloride (Cl) is negatively charged due to the addition of an extra electron. The two ions interact with each other via an ionic bond.
At this point, you need to understand “what is an ionic bond?”. Ionic bond refers to a bonding where atoms are bound by the attraction of oppositely charged ions. Since opposite charges are greatly attracted to each other that why ionic bonds are very strong. As a result, ionic compound tends to form crystalline salts in the solid form that are highly structured. These lattice structures are highly ordered special networks of the ions in three- dimensional space. Due to these highly stable crystal structures, it takes a lot of energy to disrupt this crystalline network and convert the solids into liquids. As a result, ionic salts have a high melting point.
