If a solubility curve rises upward, what does it generally mean?
Answer and explanation
Correct answer: Solubility increases with temperature
Assuming the usual graph convention, temperature is plotted on the horizontal axis and solubility on the vertical axis. An upward-sloping curve therefore means that the solubility value increases as temperature increases. It does not mean that solubility is zero or that the solvent changed. The exact interpretation should always be confirmed by reading the axis labels and scale.
