Magnesium sulfat adalah senyawa kimia, suatu garam dengan rumus MgSO4, yang tersusun dari kation magnesium Mg2+ (20,19% b/b) dan anion sulfat SO2−4. Senyawa ini berbentuk kristal padat, yang larut dalam air tetapi tidak larut dalam etanol.

Magnesium sulfat biasanya dijumpai dalam bentuk terhidrasi MgSO4·nH2O, dengan nilai n yang beragam antara 1 dan 11. Bentuk terhidrasinya yang paling umum adalah magnesium sulfat heptahidrat MgSO4·7H2O, yang dikenal sebagai garam Epsom, yaitu bahan kimia rumah tangga multiguna, termasuk garam mandi.[1]

Penggunaan utama magnesium sulfat adalah pada bidang pertanian, untuk memperbaiki tanah yang kekurangan magnesium (suatu zat gizi tanaman esensial karena magnesium berperan penting dalam klorofil dan fotosintesis). Bentuk monohidratnya dipilih untuk penggunaan ini. Pada pertengahan tahun 1970an, produksi tahunannya mencapai 2,3 juta ton per tahun.[2] Bentuk anhidrat dan beberapa hidratnya terjadi di alam sebagai mineral, dan garamnya adalah komponen air yang penting dari beberapa mata air.

Hidrat

Magnesium sulfat dapat mengkristal sebagai hidratnya, antara lain:

Hingga tahun 2017, keberadaan heksahidrat belum dikonfirmasi.[7]

Semua hidratnya akan membebaskan air kristalnya ketika dipanaskan. Di atas suhu 320 °C, hanya bentuk anhidratnya yang stabil. Ia terdekomposisi tanpa meleleh pada 1124 °C membentuk magnesium oksida (MgO) dan belerang trioksida (SO3).

Garam rangkap

Terdapat garam rangkap yang mengandung magnesium. Ada beberapa yang dikenal sebagai naterium magnesium sulfat dan kalium magnesium sulfat. Campuran tembaga-magnesium sulfat heptahidrat (Mg,Cu)SO4·7H2O baru-baru ini ditemukan terdapat pada tailing tambang dan mineral tersebut diberi nama alspersite.[8]
