Eutectic temperature of Nacl and water solution?
Sodium chloride and water form a eutectic mixture. It has a eutectic point of −21.2 oC and 23.3%salt by mass.The eutectic nature of salt and water is exploited when salt is spread on roads to aid snow removal, or mixed with ice to produce low temperatures (for example, in traditional ice cream making).
Why the eutectic mixture is not a compound?
The elements or compounds that make up a eutectic mixture keep their identities - they are merely mixed together, not combined chemically. They are completely miscible with one another as liquids, but completely immiscible with one another as solids. When a eutectic is solid (below its melting point) it consists of separate crystals or solidified droplets of the pure constituents. In the liquid state, they are merely dissolved in each other, but do not react chemically to form new compounds. It's worth mentioning that in some respects the eutectic (lowest melting) composition does indeed behave much like it's a compound unto its own right, but it's NOT. Again, no chemical reaction involved.
Where can I find eutectic points of potassium formate with ammonium nitrate and urea?
I believe the urea eutectic mix as well as those for several other salts are listed in the ASHRAE (American Society of Heating, Refrigerating, and Air-conditioning Engineers) Handbook. http://www.ashrae.org/
Alloyed with copper to make brass?
Zinc
Can you calculate the melting point of an alloy?
You need to state the alloy you're trying to melt - an iron alloy melts at a higher temperature than an aluminum alloy, and it melts at a lower temperature than a titanium alloy.
What does soldered mean?
Solder is a eutectic alloy used for bonding two pieces of metal together.
What is know as eutectic?
the question doesnt make sense
Is The melting temperature of an alloy is generally lower than its constiuants?
The melting temperature of an alloy is generally lower than the melting temperature of the highest melting temperature of all of its constituents. The eutectic melting temperature is the lowest melting temperature of an alloy system and is in fact sort of defined by that optimal set of percentages of those constituents. The next obvious question is whether there are calculation methods or approximations to determine the melting range of less than "eutectic" percentages.
What is the meaning of pro-eutectic and eutectic?
there is no difference.

When was Castolin Eutectic created?
Castolin Eutectic was created in 1906.
What is Castolin Eutectic's population?
The population of Castolin Eutectic is 2,000.
What is the eutectic pont?
Eutectic is a binary system of two substances which are miscible in all proportions in the liquid (molten) phase but do not react chemically. They have the property of lowering each others freezing point. The minimum freezing point attained is called Eutectic point and composition corresponding to Eutectic point is called Eutectic mixture. This type of system is called Eutectic system.
How does a eutectic fridge work?
"Eutectic" refers to a mixture or alloy that has the lowest possible melting / freezing point. In a true eutectic solution, all its consituents move from solid state to liquid and vice versa simultaniously as in water. The "eutectic point" is thus the freezing / melting point of the whole solution. The term "eutectic fridge" refers to a fridge that has an internal tank filled with a eutectic solution. The fridge works normally with a compressor and coolant gas, the eutectic solution is not circulated through the evaporator. When the fridge is running, it pulls down the temperature of the eutectic tank solution, which then helps keeping the temperature low even when the fridge is not running. A poor man's eutectic would be putting a lot of bottled water in your fridge and then run the fridge until all the water is cold. Now the cold liquid helps keeping down the temperature, while cold air escapes as soon as you open the door. Eutectic fridges are often used in vehicles and boats that must be self-sufficient with their electricity. The "eutectic plate" is chilled while there is plenty of power (=the engine is running, or the sun hits the solar panels etc. ), thus enabling the user to save power at times when no charge is coming to the batteries.
What is the significance of eutectic point?
The eutectic point of a mixture is defined as the temperature at which a eutectic mixture freezes or melts. A eutectic mixture is a mixture that melts and solidifies at a single temperature that is lower than the melting points of the individual constituents.
What is the difference between eutectic and eutectoid points?
The eutectic point of a mixture is defined as the temperature at which a eutectic mixture freezes or melts. A eutectic mixture is a mixture that melts and solidifies at a single temperature that is lower than the melting points of the individual constituents.
What is the difference between hypo-eutectic and hyper-eutectic steel?
hyper-eutectic steel usually has a higher carbon content compared with that of the hypo-eutectic steel.
