In this way, it doesn't matter much what the actual percentages of the two salts are, so long as there is some of both in the mixture. |

You can have a eutectic mixture of two or more salts with water. However in this case the eutectic point is normally not much reduced below the value for the salt with the lowest individual eutectic. For instance However, the eutectic point for a mixture of several salts with water is normally close to the eutectic for the salt with the lowest eutectic point with water. For instance calcium chloride combined with magnesium chloride (eutectice -33.4 °C) has a eutectic of -50.8 °C and on its own, the eutectic is -50.1 °C<ref name="TonerCatling2014"/>. |
