Waa maxay Phenolphthalein cas 77-09-8?

Phenolphthalein waa asiidh dabiici ah oo daciif ah, kaas oo u muuqda sida kiristaalo cad ama wax yar huruud ah heerkulka qolka. Waa mid aan ur lahayn oo aan dhadhamin. Way adagtahay in lagu milmo biyaha laakiin si fudud ayaa loogu milmi karaa khamriga (ethanol) iyo ether. Waxay ku milmay alkohol si loo sameeyo tilmaame-saldhig acid. Waa mid aan midab lahayn oo xal aashitada ah iyo guduudka xalalka alkali ama xalalka carbonate alkali ee birta ah. Si kastaba ha noqotee, haddii ay ku jirto xalalka alkali ee xoogga leh, waxay soo saari doontaa trimetallic acid aan midab lahayn. milix, midabka cas wuu libdhay

Codsiga

1. Qalabka ceeriin ee dawooyinka ee warshadaha dawooyinka: ku habboon calool-istaagga caadiga ah iyo madax-adayga, oo laga heli karo kiniinnada, suppositories iyo foomamka kale ee qiyaasta.

2. Phenolphthalein loo isticmaalo isku-dhafka dabiiciga ah: inta badan waxaa loo isticmaalaa balaastikada synthetic, gaar ahaan isku dhafka naphthyridine polyaryl ether ketone polyaryl ether ketone polymers. Noocan polymer wuxuu leeyahay iska caabbinta kulaylka aad u fiican, caabbinta biyaha, iyo caabbinta kiimikada. Sababtoo ah caabbinta daxalka, caabbinta kuleylka kulaylka iyo habaynta wanaagsan iyo qaabaynta, fiilooyinka, dahaarka iyo walxaha isku dhafan ee laga sameeyay ayaa si dhakhso ah loogu isticmaalaa qalabka elektiroonigga ah, qalabka farsamada, gaadiidka, hawada sare, injineernimada tamarta atomiga iyo goobaha milatariga.

3. Phenolphthalein oo loo isticmaalo tusaha acid-saldhigga, tusaha titration ee xalalka aan biyo-biyoodka ahayn, iyo reagen ee falanqaynta chromatographic.
