Answer:

As temperature increases, its solubility increases as well. Notice, however, that it does not increase significantly. In fact, you can expect to be able to dissolve no more than 40 g of sodium chloride per 100 g of water at 80∘C .

You can determine how many grams of sodium chloride, commonly known as table salt, can be dissolved in

100 g

of water at

80

C

by taking a look at its solubility graph.

A substance's solubility graph tells you how its solubility changes, let's say starting from room temperature, when temperature is either decreased or increased.
