So I'm somewhat confused about the solubility of Sodium Chloride. For Potassium Chloride, we know that it absorbs a lot of heat as it absorbs, which causes an endothermic reaction and its solubility curve to be a concave up curve. BUT, I thought that Sodium Chloride was a very good heat absorber too, so why does it have a relatively flat solubility curve where a rise in temperature does very little to the solubility?

I guess my real question is: What is the correlation between solubility curves and heat absorption?

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.

level 4 to level 2 : ))
