Hypophosphorous acid decomposition

Rhodanide - 2017-05-03

I heated Hypophosphorous acid to decomposition. Hypophosphorous acid disproportionates at high temperatures into Phosphine, which ignites. WARNING- THE P2O5 PRODUCED IS TOXIC AND QUITE CORROSIVE. PHOSPHINE IS TOXIC AND IGNITES SPONTANEOUSLY.  DOING REACTIONS ON PEPSI CANS IS QUITE UNPROFESSIONAL AND TACKY.

I like how it fluoresces at the end.

Rhodanide - 2017-06-08

Dave B Me too, looked even more spectacular IRL.

Beautiful!

Frankium - 2017-05-25

That's really cool to watch! The distinct luminescence probably comes from phosphorus formed as the PH3 breaks apart and oxidizes. I recommend that you use a piece of notebook paper to write down the exact chemical equations. Awesome video!

Frankium - 2017-05-25

Azide Yeah, I meant including the chemical equations in the video. It helps everyone to understand exactly what is happening

Rhodanide - 2017-05-25

Frankium I don't talk in my videos really that much, but I can try in the future.

Frankium - 2017-05-25

Azide you don't necessarily have to talk if you don't want to, just including the reaction itself somewhere in the video or description works fine. Keep up the good work!

Rhodanide - 2017-05-25

Frankium I'll try that. Thanks for the kind words.

Frankium - 2017-05-25

Azide of course! I finally got the chance to watch a few of your vids, I've subbed and I'll keep a lookout for more vids!

AllChemystery - 2017-05-04

well, that is pretty neat. what made you do this experiment? you really need to get a tripod!

Rhodanide - 2017-05-04

Saw CP's video and had to do it for myself.
As for the tripod, #job-less
(Soon :D )

Rhodanide - 2017-05-04

What I loved the most was when at around 0:50 the Phosphine was being emitted in small amounts, making it look like a small wave of electric fire was flickering over the surface :D

Chemistry'sCuriosities Cannagorilla - 2020-10-10

How did you get all the sodium ions out? Assuming you made it with sodium hypophosphite.

Gabriel Lay - 2018-02-25

Wow!!!!!!!!!

Rhodanide - 2018-02-25

Gabriel Lay
Indeed!
:)

Gabriel Lay - 2018-02-26

Rhodanide I wish it was easily attainable thank you for the science most interesting reaction I've ever seen possibly I'll do my best to push your subscriptions

Rhodanide - 2018-02-26

Thank you so much, Mr. Lay!
Unfortunately, Hypophosphorous acid is used in making some types of drugs. I assure you that's not the purpose of it in my possession, as I'm aggressively opposed to any and all illegal drugs.
There are so many more cool reactions out there, I implore you to do more research and find out what interests you in chemistry!

Earth storm from space...thub up.....:-)

Rhodanide - 2017-05-04

Laboratory of Liptakov No way, that's exactly what I thought!! My brother said it looked like a sports stadium.

Laboratory of Liptakov - 2017-05-04

Well..for my is it storm, respectively flashes from space. ..:-)

Chemistry'sCuriosities Cannagorilla - 2018-08-26

Looks exactly like lighting from space

Kaha milega hypophosphoric acid h4p2o6

Rhodanide - 2020-09-23

Haipophosphorik ke lie? laal phaasphoras aur NaClO2, aamataur par. Aasha hai ki ye aapakee madad karega. (Google translated, forgive me :p )

cameron Gibbs - 2018-12-22

Where did you get your Hypophosphorous acid from

Rhodanide - 2018-12-22

I didn't buy it, I made it.

Oit Thegroit - 2020-06-26

@Rhodanide How do you make it? I'm very interested.

Rhodanide - 2020-06-26

@Oit Thegroit Back when ChemPlayer was on YouTube, they had a great video on how they made it. It's pretty simple really, it's formed from the carefully measured addition of concentrated Hydrochloric acid to solid Sodium Hypophosphite. The NaCl precipitates initially and can be further precipitated upon gentle heating, giving Hypophosphorous acid with a concentration nearing 70%.

Oit Thegroit - 2020-06-26

@Rhodanide Thank you!

FANCY SEEING YOU HERE

Chemistry'sCuriosities Cannagorilla - 2018-08-26

Where did you find phosphorus acid? I can't find it anywhere

Rhodanide - 2018-08-26

Hypophosphorous acid? LOL
You can't find it for good reason, it's a List I precursor. I made it via ChemPlayer's synthesis

Chemistry'sCuriosities Cannagorilla - 2019-05-06

Hey Rhodanide, Could 85% orthophosphoric acid be used in lieu of hydrochloric acid for the synthesis instead of HCL?

Rhodanide - 2019-05-06

I don't think so.

Chemistry'sCuriosities Cannagorilla - 2020-10-10

@Rhodanide thank you

MisterGee Marino - 2017-11-18

So... What would happen if someone were to mix Hydriodic and hypophosphorus acids?

Rhodanide - 2017-11-18

MisterGee Marino I don't believe anything would happen. They're both acids, and likely wouldn't react to form anything major.

matty 69 - 2018-05-08

MisterGee Marino mix iodine phosphinic and psuedo ephdrine. See what happens then.
