Question
) The diagram shows the structure of potassium iodide.Explain why a high temperature is needed to melt potassium iodide.
Solution
Potassium iodide is an ionic compound, which means it is made up of positively charged potassium ions and negatively charged iodide ions. These ions are held together by strong electrostatic forces of attraction, also known as ionic bonds.
In order to melt potassium iodide, a significant amount of energy is required to overcome these strong ionic bonds. This energy is typically provided in the form of heat, which is why a high temperature is needed to melt potassium iodide.
The high melting point of potassium iodide is a general property of ionic compounds, as they all have strong ionic bonds that require a lot of energy to break.
