Before proceeding to drying by evaporation in an all-glass high-vacuum apparatus of the Stock type, a preliminary treatment with magnesium perchlorate (‘Anhydrone’) was given.
However, Hanley says magnesium perchlorate can depress the freezing point by 67 degrees Celsius. Perchlorate is so soluble in water, that the only place it can accumulate is in very dry regions.
That fact serves as something of a marker for how long water was present on the planet, with the lowest parts of the mountain rich in hydrated salts like magnesium perchlorate, magnesium chlorate ...
The magnesium perchlorate is clearly a major contributing factor on the freezing point of this solution and paves the way for understanding how a fluid might exist under the sub-freezing ...
But first, NASA's rover has to play bartender to make sure the dry dust is shaken, ... The water is believed to contain certain salts — not ordinary table salt, but magnesium perchlorate, ...
The researchers put magnesium perchlorate under short-wave UV radiation, similar to conditions on the surface of Mars, and found that under these conditions, the magnesium perchlorate killed all ...
They mixed up a plausible concentration of magnesium perchlorate brine and filled the headspace in that container with pure CO 2 for a Mars-like atmosphere. The whole thing was kept at -36°C (-33 ...
