Solubility & Saturation

\text{Solubility} = 10 + 2 \times 20 = 50 \text{ g}

Solubility limit50 g

Amount dissolved30 g

Stateunsaturated

If cooled to 10°C, crystallises0 g

Temperature (°C)20

Amount added (g per 100 g water)30

Select Potassium nitrate and set temperature to 20°C — confirm the solubility limit reads 50 g
Select Sodium chloride and push temperature to 100°C — confirm the limit is still about 36 g (barely changed)
On Potassium nitrate at 20°C, set the amount to exactly 50 g — confirm the state reads SATURATED
On the same Potassium nitrate at 20°C, push the amount above 50 g — confirm the state reads SUPERSATURATED
Select Potassium nitrate, set temperature to 60°C and amount to 130 g (saturated) — cooling to 10°C should crystallise 100 g
