Introduction: Hot Ice

About: I am an undergraduate student pursuing B.Tech in EEE(Electrical and Electronics Engineering).I am passionate about creating new stuffs using technology and hungry to learn more and more.

Sodium acetate or hot ice is an amazing chemical you can prepare yourself from baking soda and vinegar. You can cool a solution of sodium acetate below its melting point and then cause the liquid to crystallize. The crystallization is an exothermic process, so the resulting ice is hot. Solidification occurs so quickly you can form sculptures as you pour the hot ice.

Step 1: Chemicals Reuired

>4 tablespoon Baking soda

>500 ml Vinegar

>2 ml Water

Step 2: Materials Required

>steel vessel

>transparent container


>measuring cup

Step 3: Measure 500ml of Vinegar

I am using a 100 ml measuring cup .

Transfer this vinegar into a vessel.

Step 4: Add Baking Soda to Vinegar

The baking soda and vinegar react to form sodium acetate and carbon dioxide gas.

If you don't add the baking soda slowly, you'll essentially get a baking soda and vinegar volcano, which would overflow your container.

Step 5: Heat the Solution

You've made the sodium acetate, but it is too dilute to be very useful, so you need to remove most of the water.Here is the reaction between the baking soda and vinegar to produce the sodium acetate:

Na+[HCO3]– + CH3–COOH → CH3–COO– Na+ + H2O + CO2

Since the reaction itself produces water as a byproduct there is no need to add water but if the content get thicken add 2 ml water.

Heat the mixture and stir constantly for some time.

Set the soultion to cool down and left unagitted.

Step 6:

Once you remove the sodium acetate solution from heat, immediately cover it to prevent any further evaporation.

Pour the solution into a separate container.

I covered the container with foil paper.

Step 7: Look Out for Results

Remove the solution from the refrigerator after cooling the solution for 30 minutes .

Insert any foreign object which would agitate the solution .

The sodium acetate will crystallize within seconds, working outward from where you agitated the solution .
