A yellow anhydrous salt reacts with water to form a green hydrated salt.
| Substances at the start | Initial temperature | Highest temperature | Solid at the end |
|---|---|---|---|
| Yellow anhydrous salt and water | 20.0 °C | 28.5 °C | Green hydrated salt |
A sealed container holds an equilibrium mixture of the green hydrated salt, the yellow anhydrous salt and water vapour.
Use the results in the table to explain which coloured solid will increase in amount when the equilibrium mixture is heated.
