SUnknownAzides: Sodium Azide NaN3 and Lead Azide Pb(N3)2

Sat, Jan 20, 2018

Felix ignites sodium azide which decomposes to sodium metal which itself ignites leaving behind the still quite reactive chemical sodium peroxide. He does a similar demonstration with lead azide which was loaded into the hollow point bullets used in the assassination attempt on Ronald Reagan.

SUnknownHot 5 chemical reactions from subscribers

Sun, May 27, 2018

Felix performs five reactions requested by his viewers. Needless to say, the reactants are pretty reactive in any situation and some are rather uncommon. But what these reactions all share is a penchant for combustion in flames or explosion..

SUnknownEpisode dated 21 June 2018

Wed, Jun 20, 2018

Felix attempts to react red phosphorus with hot water as Walter White did in "Breaking Bad" to escape from gangsters. No reaction. He should have used a metal phosphide. So Felix cooks up some magnesium phosphide which he reacts with water to generate the desired toxic phosphine gas.

SUnknownSOCl2: Thionyl chloride

Thu, Jun 28, 2018

Thionyl Chloride is a colorless acrid liquid that hydrolyzes to sulfur dioxide and hydrochloric acid. Felix reacts cobalt (II) chloride hexahydrate which changes from pink to blue as the water is consumed by the thionyl chloride. He also demonstrates highly exothermic reaction of thionyl chloride with various metals.

SUnknownB2H6: Diborane. Synthesis and burning

Fri, Oct 19, 2018

Felix prepares diborane in a simple test tube reaction of sodium borohydride and stannous chloride. The reaction begins in the solid state but becomes vigorous when the reactants are heated to melting. Felix doesn't try to isolate the diborane but ignites the vapors to show a green flame.

SUnknownNOClO4: Nitrosyl perchlorate

Fri, Nov 09, 2018

Since it's not commercially Felix prepares nitrosyl perchlorate by the established method of reacting nitrogen oxides with perchloric acid. If it sounds like nitrosyl perchlorate is a reactive chemical, it is, so now the fun begins. It reacts explosively with organic compounds with oxygen functional groups and the more reactive metals.

SUnknownSm: Samarium element, chemical reactions

Thu, Nov 22, 2018

Samarium is a reactive lanthanide metal the oxidizes in air and reacts slowly with water. Felix finds it is highly reactive with oxygen, the halogens chlorine, bromine and iodine, the superoxides of barium and potassium and dinitrogen trioxide to the point of combustion.

Thu, Dec 06, 2018

Felix spares us the barking dogs experiment to do some real carbon disulfide chemistry. He synthesizes sodium ethyl xanthogenate and from it precipitates the copper salt He demonstrates the brilliant blue flame of burning sulfur dissolved in carbon disulfide and the spontaneous combustion of chlorine dioxide in carbon disulfide.

Thu, Feb 07, 2019

Felix performs five quick reactions mostly in the solid state: zirconium powder with frozen sulfur hexafluoride, strontium powder with strontium nitrate, germanium powder with chlorine gas, and lithium borohydride with both Chromyl chloride and potassium peroxide. Things get hot.

SUnknownRe2O7: Rhenium Heptoxide. Chemical reactions

Mon, Apr 01, 2019

Rhenium heptoxide is a rare and expensive yellowish green compound. It sublimates at low temperature condensing into a liquid before recrystallizing. Although a weak oxidizer it readily reduces hydrobromic acid to bromine. Felix demonstrates various other redox reactions of the chemical. often with colorful products.

SUnknownH2Se: Hydrogen selenide. Red selenium

Tue, Nov 12, 2019

Molten selenium reacts with the more reactive metals such as sodium, potassium and aluminum, to produce the selenide salts. Reacting them with a strong acid produces hydrogen selenide. The selenides can also be reduced to produce red selenium.

SUnknownTiH2: Titanium (II) Hydride. Solid Hydrogen Solution

Wed, Jan 08, 2020

Titanium dihydride is a gray, non-stoichiometric compound that is never quite 1:2. It grows darker as it absorbs hydrogen. Ironically although titanium powder and hydrogen are highly flammable the hydride is much less so. But Felix can't resist mixing in a little perchlorate to start some fireworks.

SUnknownInterhalogen Compound: ICl3 Iodine Trichloride

Fri, Jan 31, 2020

Iodine trichloride is a yellow fuming solid that thermally decomposes to iodine monochloride and chloride. Flexic reacts this compound with sulfuric acid, potassium hydroxide, tin II chloride, red phosphorus, lithium borohydride, hydrazine and decaborane. Many of the solid mixtures spontaneously ignite.

SUnknownRubidium ampoule opened in Air for chemical reactions

Fri, Feb 21, 2020

Felix has acquired some costly samples of rubidium. Of course it reacts with water but it is surprisingly resistant to even pure oxygen or ozonated oxygen. Iodine trichloride, oleum and, with a little 'compression', boron tribromide, are much more accommodating. Felix loses a couple watch glasses when rubidium reacts a little to vigorously with iodine and bromine.

SUnknownOzonides! Potassium and Cesium Ozonides. KO3, CsO3

Tue, Mar 17, 2020

As potassium and cesium hydroxide and potassium superoxide are exposed to ozone the reactant becomes yellow then red as the ozonides are produced. The ozonides decompose as they warm sometimes explosively. Felix also reacts potassium with ozone after first dissolving the metal in liquid ammonia.

SUnknownLiquid ammonia and Chromium(III)Oxide. NH3 + Cr2O3

Thu, Apr 23, 2020

Felix is determined to burn ammonia. A direct flame doesn't work so lets try some chromium compounds. Potassium dichromate burns easily on it's own but ammonia won't make it burn. Ammonia won't even burn with the resultant hot chromium(III) oxide. What about potassium chlorochromate?

Tue, Jul 07, 2020

Moylbdenum pentachloride is a black solid. Felix reacts it with air, water and hydrochloric acid to produce various oxychlorides in a rainbow of colors.

SUnknownInterhalogen compound: IBr Iodine monobromide

Sun, Apr 04, 2021

Iodine monobromide is a solid resembling iodine but it releases red fumes rather than violet. In the molten state it is a deep red liquid. Felix reacts this reagent with sulfuric acid, potassium hydroxide, hydrazine, potassium, copper, red phosphorus, antimony and aluminum. The more energetic reactions produce copious red vapors and some reaction occur in the solid state.
