What happens when you mix Styrofoam with acetone?
What happens when you mix Styrofoam with acetone?
The Styrofoam will dissolve in the acetone much like sugar dissolves in hot water. Since Styrofoam is mostly air, you may be surprised by how much (or, in the end, how little) foam will dissolve in the acetone. A cup of acetone is enough to dissolve an entire bean bag’s worth of styrofoam beads.
What is the chemical formula for acetone and Styrofoam?
(CH3)2CO
It is an organic compound with the formula (CH3)2CO. A colorless, flammable solvent, it mixes easily with water and evaporates quickly in the air, and is the simplest example of the ketones. Like Styrofoam, acetone is a non-polar molecule. It is an important solvent, often used to clean things in the laboratory.
Is acetone and Styrofoam endothermic or exothermic?
Every chemical reaction that exists is one of two things: endothermic or exothermic. The Greek root therm means temperature or heat, which gives us a clue about all reactions: there is energy exchange!…Procedure.

How do you make Styrofoam formula?
Things You’ll Need
- 2 tsp. borax.
- 1/2 cup water.
- 1/4 cup Elmer’s glue.
- 1/4 cup water.
- Air-tight plastic bag, gallon size.
- 2/3 cups micro-beads (1mm in diameter)
- 1 cup 1/8-inch bean bag filler beads.
What gas is released when you burn styrofoam?
The burning of polystyrene releases styrene gas which can effect the nervous system. Also, as it usually burns with a sooty flame, this indicates combustion isn’t complete and a complex mixture of toxic chemicals can produced by the relatively low temperature of a backyard burn.
What is the chemical formula of acetone?
C3H6OAcetone / Formula
What gas is released when you burn Styrofoam?
Why does Styrofoam dissolve in acetone but not water?
Acetone is a relatively non-polar solvent (as compared to water, which is highly polar), and Styrofoam is made from polystyrene and foam. Due to their similar polarities, acetone can dissolve the carbon-hydrogen bonds of Styrofoam.
How do you test for exothermic and endothermic reactions?
When energy is released in an exothermic reaction, the temperature of the reaction mixture increases. When energy is absorbed in an endothermic reaction, the temperature decreases. You can monitor changes in temperature by placing a thermometer in the reaction mixture.
What is the chemical makeup of Styrofoam?
Styrofoam is a petroleum-based polymer, meaning that it is made from oil. Styrofoam is made of the polymer polystyrene, where styrene is the repeating monomer. Styrene is composed only of carbon and hydrogen.
How do you turn Styrofoam into glue?
- Pour acetone into a metal, glass or ceramic dish until the base of the dish is covered.
- Place a Styrofoam item into the acetone bath and gently press down on it.
- Continue pressing Styrofoam pieces into the acetone bath until you have a batch of glue and no more pure liquid acetone.
What happens to Styrofoam when it burns?
Burning Styrofoam, or polystyrene, is the least appropriate way to get rid of it for both people and the environment. Research has shown that when Styrofoam is burned it releases toxic chemicals and smoke that can damage the nervous system and lungs.
Is melted Styrofoam toxic?
Vomiting, nausea, headaches and diarrhoea are among the side effects of eating food products in slightly melted Styrofoam. Reheating the food together with the container exacerbates the problem. Styrofoam is also a threat to marine life. It is non-biodegradable and will break into small pieces when discarded.
What does acetone react with?
Acetone reacts with OXIDIZING AGENTS (such as PERCHLORATES, PEROXIDES, PERMANGANATES, CHLORATES, NITRATES, CHLORINE, BROMINE and FLUORINE); ACETIC ACID; and NITRIC ACID to form explosive peroxides. Acetone attacks PLASTICS.
What is the solubility of Styrofoam in acetone?
Polymers, Solubility, and Recycling When styrofoam is added to acetone (a common organic solvent) it very rapidly dissolves, making it look like it is disappearing. Starch-based packing “peanuts”, on the other hand, will not dissolve in acetone, but do readily dissolve in water.
Is acetone and Styrofoam flammable?
The solvent is very flammable and can be harmful if inhaled, so use safety when conducting this experiment! First: Pour ½ cup of acetone into the bowl. Second: Slowly lower a Styrofoam cup into the acetone. Observe the reaction between the acetone and the Styrofoam.
What is the equation for exothermic reaction?
The general equation for an exothermic reaction is: Reactants → Products + Energy. Note: ΔH represents the change in energy. If the energy produced in an exothermic reaction is released as heat, it results in a rise in temperature.
What is an endothermic equation?
The general equation for an endothermic reaction is: Reactants + Energy → Products. [Figure 2] Note: ΔH represents the change in energy. In endothermic reactions, the temperature of the products is typically lower than the temperature of the reactants.
