| Properties | Details |
| Combustibility | Non-combustible substance |
| Decomposition | Upon heating, Epsom salt decomposes to release water and anhydrous magnesium sulfate (MgSO4) |
| Hydrate Formation | Epsom salt readily forms hydrated crystals with water molecules, such as the heptahydrate |
| pH | Epsom salt is neutral, with a pH around 7.0 |
| Reaction with Acids | Reacts with acids to produce magnesium sulfate and release carbon dioxide |
| Reaction with Alkalis | Reacts with alkalis to precipitate insoluble magnesium hydroxide |
| Reaction with Water | Dissolves readily in water, forming a clear, colorless solution |
| Reducing Agent | Can act as a mild reducing agent in certain chemical reactions |
