CHEMICAL FORMULA FOR HYDROGEN PEROXIDE SKIN
Wash skin: WHEN CONTAMINATED - The worker should immediately wash the skin when it becomes contaminated. Skin: PREVENT SKIN CONTACT - Wear appropriate personal protective clothing to prevent skin contact.Įyes: PREVENT EYE CONTACT - Wear appropriate eye protection to prevent eye contact. Įxcerpt from NIOSH Pocket Guide for Hydrogen peroxide : Hydrogen selenide and hydrogen peroxide undergo a very rapid decomposition. Mixtures of hydrogen peroxide and 1-phenyl-2-methyl propyl alcohol tend to explode if acidified with 70% sulfuric acid. Mixtures of ethyl alcohol with concentrated hydrogen peroxide form powerful explosives. Example: An explosion will occur if dimethylbenzylcarbinol is added to 90% hydrogen peroxide then acidified with concentrated sulfuric acid. Mixtures of alcohols with concentrated sulfuric acid and strong hydrogen peroxide can cause explosions. During concentration under vacuum of aqueous or of aqueous-alcoholic solutions of hydrogen peroxide, violent explosions occurred when the concentration was sufficiently high(>90%). Concentrated peroxide may decompose violently in contact with iron, copper, chromium, and most other metals or their salts, and dust(which frequently contain rust). Solvents(acetone, ethanol, glycerol) will detonate on mixture with peroxide of over 30% concentration, the violence increasing with concentration. Readily oxidizable materials, or alkaline substances containing heavy metals may react violently.

Contamination of concentrated peroxide causes the possibility of explosion. Most cellulose materials contain enough catalyst to cause spontaneous ignition with 90% peroxide. There is a release of enough energy during the catalytic decomposition of 65% peroxide to evaporate all water and ignite nearby combustible materials. 1 p.101.The hazards associated with the use of HYDROGEN PEROXIDE (especially highly concentrated solutions) are well documented. and Ealy, J.L., Chemical Demonstrations – A Sourcebook for Teachers vol. et al, A Demo a Day – A Year of Chemical Demonstrations, Flinn Scientific, p 55. The foam and solution left in the cylinder may be rinsed down the drain with copious amounts of water. Safety goggles and gloves should be worn during the demonstration. Do not stand over the reaction – steam and oxygen are quickly produced. The possible presence of a brown color in the foam is evidence of iodine in the reaction vessel.Ĭare should be taken handling 30% hydrogen peroxide – it is severely corrosive to the skin, eyes and respiratory tract. Since this is an exothermic reaction, steam may be seen emerging from the cylinder. The generated oxygen interacts with the soap creating a foam “snake” which quickly fills the cylinder and spills onto the large serving tray.
CHEMICAL FORMULA FOR HYDROGEN PEROXIDE PLUS
Quickly pour the 2 M KI solution into the 500 mL graduated cylinder containing the hydrogen peroxide plus soap and stand back. Measure 5 mL of 2 M KI solution in 10 mL graduated cylinder.

Add 5 mL dishwashing liquid and 10 drops food coloring to the graduated cylinder and shake to mix contents, but not too vigorously to avoid foaming. Measure 20 mL of 30% hydrogen peroxide into the graduated cylinder.Large serving tray and rubber gloves to assist in cleanup.Dishwashing liquid – approximately 5 mL.Potassium iodide 2 M – Prepare stock solution by mixing 33.2 g KI in distilled water and dilute to 100 mL.20 mL 30% hydrogen peroxide, available from chemical supply establishments.The decomposition of hydrogen peroxide in the presence of iodide ion occurs in two steps: The rapid evolution of oxygen gas is produced by the following reaction: Procedure presents an example of a catalyzed reaction.

This is the classic “Elephant Toothpaste” reaction. Two solutions are mixed resulting in an eruption of foam resembling a huge stream of toothpaste.
