Using the solubility curve, what is the effect of increased temperature on the solubility of KBr in 100 grams of water? The solubility is uniform. The solubility increases. The solubility decreases. The effect cannot be determined from the curve.

The graph is needed to answer this question.

Solubility may increase or decrease with temperature depending on the properties of the solute and the solvent.

It is quite common that the solubility of the ionic compounds, like KBr, in water increases with temperature.

Use your solubility curve for the KBr and you wiil see a line that starts at a solubility a little greater than 50 grams of the salt in 100 grams of water for temperaute 0°C and increase linearly until almost 100 grams of the salt in 100 grams of water at 100°C.

So, in this case you can affirm that the solubility of KBr increases with the temperature.

Answer: the second option: the solubility increases.
