Solubility of Selected Substances A line graph plotting the solubility of five substances in water across a temperature range of 0 to 100 degrees Celsius. The y-axis shows mass dissolved in grams per 100 milliliters of water, ranging from 0 to 260 g. Each substance uses a unique color and line pattern. KNO₃ (potassium nitrate, purple dotted line) shows the steepest rise, reaching approximately 246 g at 100°C. NaClO₃ (sodium chlorate, orange dash-dot line) starts highest near 80 g at 0°C and reaches about 204 g at 100°C. KBr (potassium bromide, red solid line) increases gradually from about 53 g to 104 g. CuSO₄ (copper sulfate, blue long-dash line) rises from 14 g to 75 g. NaHCO₃ (sodium bicarbonate, teal dashed line) remains nearly flat and is only shown to 60°C because it begins to decompose at higher temperatures, ending near 16 g.
