Kungi, es veicu šo eksperimentu, un es to uzsildīju līdz 125 grādiem, jo, uzkarsējot fosforskābi līdz 130 grādiem, radīsies fosfātūdeņraža gāze (toksiska). Vai ir kāds veids, kā no tā izvairīties?

Jūs varat izmantot PH3 absorbciju ar NaClO un NaOH
H3PO2 iznīcina 170 C temperatūrā

Sveiki, vai ir kāda atšķirība, ja šajā recepte izmantoju sudoefedrīnu ?

You want a molar equivalent , these are hypothetical amounts, but say the the 6g of ephedrine is 20mmol of one mol of ephedrine then you'd want 20mmol equivalent of pseudo.im by no mean a pro and have never even looked up the molecular weight of either of them put that's the idea .
There's a post on here somewhere I believe from patten that is very detailed and informative about the subject definitely look it up because this is something that is very important in all reactions.
Sincerely B

Sveiki, man ir jautājums: vai joda vietā varētu izmantot kālija jodu? Jo Kālija Idodīns ir daudz vieglāk nopērkams.

Sveiki, nē. Šīm vielām ir atšķirīgas ķīmiskās īpašības.

Joda pagatavošanai var izmantot joda potasiju. To var izdarīt laiskā svētdienas pēcpusdienā.

Sveiki, nē, jūs nevarat lietot ne jodūdeņražskābi, ne fosforskābi.

Jautājiet atbildes ekspertiem, jo man tas nav izdevies un esmu iztērējis daudz naudas un materiālu.

Skolotāj, vai es varu izmantot DCM tā vietā bez destilācijas un pārvietot to tieši uz pārsvara ūdeņraža hlorīdu?

You can do this, but it is better to extract into the water layer when acidification and evaporate part of the water. You can use aq. HCl
