How much magnesium chloride should be added to a liter of water to produce a saturated solution?
Saturated solutions of:anhydrous MgCl254.3 g/100 ml (20 °C)72.6 g/100 mL (100 °C)hexahydrate MgCl2(H2O)6157 g/100 mL (20 °C)Note:[A variety of hydrates are known with the formula MgCl2(H2O)x, and each loses water with increasing temperature:below 0°C (as de-icer): x = 12 (-16.4 °C) and x = 8 (-3.4 °C),above 100°C: x = 6 (116.7 °C), x = 4 (181 °C) and x = 2 (ca. 300 °C)]
