The rehydration salts are added to water and provide electrolytes to help people hydrate, Tidey said.
Recently, planetary scientists detected hydrated salts on these slopes at Hale crater, corroborating their original hypothesis that the streaks are formed indeed by liquid water.
we also found spectral evidence for hydrated salts on the slopes where RSL form.""Hydrated salts precipitate from liquid water,
so detecting them is a big deal especially since circumstances make it unlikely that CRISM could spot RSL water directly.
. so I think this hydrated signature of the salts is definitely a'smoking gun, '"he said.
The RSL-associated salts appear to be perchlorates, a class of chlorine-containing substances that are widespread on Mars. These salts lower the freezing point of water from 32 degrees Fahrenheit (0 degrees Celsius) to minus 94 F (minus 70 C),
Ojha said.""This property vastly increases the stability of brine salty water on Mars, "he said.
Findings show that hydrated salts are present on the surface of Mars. Hydrated salts would mean that the water on Mars is briny.
According to Popular Science, the salt in the water allows it to remain liquid at lower temperatures.

Auyeung said. he molten salts now being used to store solar thermal energy can only work at about 600 degrees centigrade,
"This has been replaced with water as the solvent and lithium iodide as the salt, which offers low-cost, high-energy storage capabilities."
Developed by a team of researchers at Alexandria University in Egypt, the procedure uses a desalination technique called pervaporation to remove the salt from sea water
"It can effectively desalinate water with high concentration of salt like that of the Red sea, where desalination costs more and yields less."
and track hydrated salts in these gullies-using an image spectrometer on the MRO, the NASA team has been able to link these salts to areas where the slope gullies
(or"linae")are at their largest, and that's the evidence they needed to suggest flowing water is the cause.
even impure metallic salts can be used as a raw material, which keeps the price low. VTT has demonstrated the practical functionality of its reactor by testing the production of various nanometals, metallic compounds and carbon-coated materials.

By feeding the animals a diet high in fat and salt over the course of a year,
Berkeley, has found that blending together different types of salts in the electrolytes within lithium air batteries can increase the batteriescapacity
Electrolytes consist of a salt and a solvent to dissolve the salt. he electrolytes used in batteries are just like Gatorade electrolytes,
says Venkat Viswanathan, assistant professor of mechanical engineering at Carnegie mellon. very electrolyte has a solvent and a salt.
So if you take Gatorade, the solvent would be water and the salt would be something like sodium chloride, for instance.
However in a lithium air battery, the solvent is dimethoxyethane and the salt is something like lithium hexafluorophosphate. arlier this year,
The paper, titled nhancing Electrochemical Intermediate Solvation through Electrolyte Anion Selection to Increase Nonaqueous Li-O2 Battery Capacity, explains that salts are the key not solvents
Then, Mccloskey came up with the ingenious idea of changing the salt instead, Viswanathan said. nstead of using just one salt,
we decided to blend salts together. We used two salts: lithium bis (trifluoromethane) sulfonimide and lithium nitrate. ande adds, y blending salts in the electrolyte solution,
we increased the battery capacity by triggering the so-called solution process without compromising on rechargeability.
Nitrate anion from the lithium nitrate salt does the trick by selectively dissolving previously insoluble products without facing the fundamental bottleneck produced by solvent additives. hough this research is an important advancement for lithium air batteries,
the methods the researchers have developed will also be very impactful in other areas of battery research. his research is going to be very important for another big battery technology,
In salt containing water, these have a natural tendency to form chains. A higher degree of attraction is exhibited on increasing the salt concentration.
