Explanation:
Potassium Iodide -
It is a salt , which is made of the ions of potassium and iodine ,
Potassium being the cation , and iodide being the anion .
The ions of this salt are held by strong ionic forces , which hold the ions together very strongly .
Hence , a lot of energy is required to melt the salt , as the bond between the ions is very strong .
Hence , the melting point of this salt , i.e. , Potassium Iodide , is very strong .
