I had in a way a very similar chemistry teacher. He could tell endless stories about countless encounters with different substances, about guys that got mercure poisoning or explosions and things that went wrong. But for sure we learned more about the nature and dangers of substances from his stories than from any of the books. One of his favorite sayings was: I´ts chemistry when it bangs and stinks. He was a scientist as well and had a degree.

lead acetate paper used to be used to remove traces of H2S when quantifying arsine evolved in the Marsh test with mercuric chloride. Mercuric chloride is specific for arsine as long as there's no H2S present along with it. It's part of the arsenic detection kit but it doesn't detect arsenic itself!

@MM-wi4dt 4 года назад

Such a lovely bunch of chemicals

@NinoNiemanThe1st 4 года назад

Thanks desange, great explanation. A shame so many of these chemicals are so toxic...still can't go up against a Marsh Test when it comes to illicit (or licit) consumpton of chemicals like As, and the colors you often get after the reaction are endlessly fascinating.

@mikeharris1002 4 года назад

That kind of ties up with my memory of using mercuric chloride papers in a quantitative test in about 1968. Some dilute sulphuric acid and and a few zinc turnings were added to a solution of the material under test and the gas that was evolved passed over a mercuric chloride paper test strip. The test strip picked up a brown stain from the gas with an intensity that was related to the concentration of arsenic in the solution under test. This was determined by comparing the stain with an incremental set of standard stains prepared under the same conditions.

@markusfaller1333 3 года назад

The test with mercuric chloride is called Gutzeit test and for that test you should fist trap hydrogen sulphide H2S out of the gas stream which contains the arsine AsH3. Normally you use a cotton ball dipped into lead acetate but it seams that you can use the lead paper instead. Nice to see how ancient chemist alleady knew so much about the chemical reactions.

To use those lead papers you have to reduce As to arsine (as you did with zinc in acid). Then the arsine gas passing through the humidified paper can reduce Pb(II) to lead metal, wich makes the paper black. I used it in our qualitative analysis lab in Pisa.

@@gamingmarcus sidenote: the reaction was between the lithium and the fluorine, while the hydrogen would get added later in the combustion chamber (so it didn't really react much).

A wonderful video! Arsenic is one of my favorite elements, maybe because I have found a 6.8 kg specimen that sits on the bottom shelf in my mineral collection. Arsenic is indeed metallic white when fresh, but turns brown to black on the surface over time. And when it sits on the mine dump a couple of years it gets a crust of white powder which makes it possible to spot it from meters away on small pebbles. A friend and I went to that mine (Storliden in Sweden) several times a year when it was active so I got somewhere around 50-100 kg of mineral specimens of arsenic. :-D Yummy!
