At what temperature do KBr and KNO3 have the same solubility? Record that solubility. At 48°C , both KBr and KNO3 have a solubility of 80.
What is the solubility of potassium nitrate?
Potassium nitrate is moderately soluble in water , but its solubility increases with temperature. The aqueous solution is almost neutral, exhibiting pH 6.2 at 14 °C (57 °F) for a 10% solution of commercial powder. It is not very hygroscopic, absorbing about 0.03% water in 80% relative humidity over 50 days.

What is solubility curve?
A solubility curve is a graph of solubility, measured in g/100 g water , against temperature in °C. Solubility curves for more than one substance are often drawn on the same graph, allowing comparisons between substances. Comparing solubility curves for a variety of compounds on a single graph.
How does temperature affect the solubility of potassium chloride?
