Why is Δsolubility / Δtemperature so much lower for NaCl than for other ionic compounds like KCl and NaNO3? (It's solubility curve is almost flat).
Could you explain further?enthropy said:It doesn't but I found the Van't Hoff equation and from there it is fairly straightforward.

NaCl's solubility curve is a graph that shows the relationship between the temperature and the solubility of NaCl in water. It demonstrates how much NaCl can dissolve in a given amount of water at different temperatures.
NaCl's solubility curve is considered to be low because it shows that the solubility of NaCl in water decreases as the temperature increases. This means that at higher temperatures, less NaCl can dissolve in water compared to lower temperatures.
The factors that affect NaCl's solubility curve include temperature, pressure, and the presence of other substances in the solution. Temperature and pressure directly influence the solubility of NaCl, while other substances can affect its solubility by changing the chemical environment of the solution.
The low solubility curve of NaCl can be explained by its strong ionic bonds. As the temperature increases, the kinetic energy of the water molecules also increases, making it more difficult for the Na+ and Cl- ions to interact and form bonds with the water molecules. This results in a decrease in the solubility of NaCl in water.
Understanding NaCl's solubility curve has various applications in different areas, such as in the production of salt solutions, food and beverage industry, and pharmaceuticals. It also helps us understand the behavior of other ionic compounds in water and provides insights into the properties of different solutions.
