Answer 1

I don’t have the solubility-curve diagram you mentioned. Please upload it (or type the solubility values from the graph for each salt at the given temperature).

How to decide once you have the graph:
- Find the solubility (g solute per 100 g H2O) for that salt at the given temperature.
- If the given mass equals the graph value → saturated.
- If the given mass is less → unsaturated.
- If the given mass is greater → supersaturated.

If you want a quick estimate using typical solubility data (may differ from your diagram):
- 45 g KCl at 60°C → slightly supersaturated (solubility ≈ 44 g/100 g H2O).
- 70 g CaCl2 at 10°C → supersaturated (solubility ≈ mid‑60s g/100 g H2O at ~10°C).
- 20 g NaCl at 50°C → unsaturated (NaCl solubility ≈ 35–38 g/100 g H2O).

Send the diagram or the exact solubility values and I’ll place each response exactly.
