The document explains the chemical phenomenon of "hot ice" which is formed when a supersaturated solution of sodium acetate is frozen. When sodium acetate dissolves in water, it forms ionic bonds between sodium cations and acetate anions. Freezing this solution causes the ions to precipitate out of solution in a solid crystalline form, releasing heat in the process and giving the illusion that the ice is hot to the touch. Chemistry teachers use this demonstration to show supersaturation, where solutions can dissolve more material than they normally should.

1. Explanation
What it is about?
In chemistry, the term "compound" refers
"Hot ice" refers to a popular to a material comprised of more than
chemical demonstration in which a one chemical element. For example, HOT ICE
solution of sodium acetate table salt, also known as sodium
dissolved in water and placed in a chloride, contains sodium and chlorine
freezer instantly solidifies when atoms. When the compound contains
poured from its container or when a
single crystal of solid sodium
both a metal and a nonmetal--as
acetate is dropped into the distinguished on the periodic table of the
solution. The solidification process elements--chemists refer to the SCIENCE FAIR
releases heat and thus gives the compound as "ionic." Some ionic
appearance of the formation of compounds dissolve in water, and during
hot ice. Chemistry instructors use the dissolution process the positively
this to demonstrate the
charged metal, called a cation,
phenomenon of supersaturating, or
the ability of some solutions to separates from the negatively charged
contain more dissolved material nonmetal, called an anion. The process
than they normally should. of precipitation represents the opposite
of this process; that is, the cation and
anion combine to form solid crystals in
the solution.The precipitation of a solid
from a solution results in decrease in the
disorder of the system. That is, in the
solution the ions move freely in random
directions and therefore exhibit high
disorder. When the ions combine to form
solid crystallites, their freedom of motion
becomes restricted. Scientists describe
this as a decrease in the entropy, or
disorder, of the system.

Conclusion
In conclusion we invite you
to demonstrate you what
you can make wit sodium
acetate, and if you have a
Procedure& Ingredients party and you want to
What is going to happen? make a status you can
make it with this. Cecilia González
First you need to put water on a pan. Paulina Martínez
When the water start to boil you put Laura Sofía Sánchez
sodium acetate, but you need to put a
lot of sodium. Then you dissolve it on the Montse García
pan. After is all dissolve you put the water
with sodium in a glass.Put it on the fridge
for 15 to 30 minutes. Then you put it on a
small glass bowl, then you touch it, or mix
it with the finger, but you need to have a
little bit of sodium in the finger and it
started to make hot ice.
What is going to happen is that you will
have hot ice and you can make shapes,
figures or status with ice.
