How To Make Hot Ice
Hot ice, such a contradictory word. How in the world is ice supposed to be hot? it’s in nature to be cold.
Hot ice isn’t called hot ice just because it’s hot, it’s called hot ice because of its behavior.
Its chemical name is Sodium Acetate and you can prepare this cool chemical right at home and store it in your lab, that’s if you have one.
You’re going to need a few simple things for this experiment
- A liter of vinegar ( acetic acid- CH3COOH ) and
- Baking soda ( Sodium Bicarbonate- NaHCO3 )
How to Prepare Hot Ice
- Take out your vinegar ( clear ) and turn the whole bottle into a pot or a beaker, try to avoid spillage so you don’t make a mess of the place. “vinegar smells awful”
- Next, you’ll need your baking soda. Take a spoon and carefully add 4 spoon fulls of baking soda into your vinegar, add slowly and little at a time to avoid a baking soda volcano.
- Stir for a while. At this point, we have our sodium acetate but the process isn’t complete yet.
- Boil your sodium acetate at low temperature till you start seeing bubbles at the top. ( it’s important you mustn’t boil at a very high temperature because if you do the sodium acetate will start turning yellowish )
- Take your pot off the heat and turn your sodium acetate into a different container making sure it’s covered to avoid evaporation. let it cool to room temperature.
And you have hot Ice, dip something into it and you should see something like this.
How It Works
The reaction of hot ice is a double displacement reaction
NaHCO3 + CH3COOH ——- CH3COO Na + CO2 + H2O
Sodium bicarbonate reacts with acetic to yield sodium acetate, carbon dioxide, and water.
The sodium acetate is an example of a supercooled liquid.
That is, the sodium acetate exists in liquid form below its usual melting point. You can initiate crystallization by adding a small crystal of sodium acetate or possibly even by touching the surface of the sodium acetate solution with a spoon or finger.
The crystallization is an example of an exothermic process. Heat is released as the ice forms giving it its name hot ice.
I want you to try this and tell me in the comment section the results you got.
