CO OZNACZA SŁOWO LITMUS TEST
Lakmus
Litmus jest rozpuszczalną w wodzie mieszaniną różnych barwników wyekstrahowanych z porostów, zwłaszcza Roccella tinctoria. Często absorbuje się ją na papierze filtracyjnym, aby wytworzyć jedną z najstarszych postaci wskaźnika pH, stosowaną do badania kwasów. Papier niebieski lakmus zamienia się w kolorze czerwonym w warunkach kwaśnych, a czerwone papiery lakmusowe zmienia się na niebiesko w podstawowych warunkach, przy zmianie koloru w zakresie pH 4,5-8,3 w temperaturze 25 ° C. Neutralny papier litowy jest fioletowy. Litmus może być również przygotowany jako wodny roztwór, który działa podobnie. W kwaśnych warunkach roztwór jest czerwony, aw podstawowych warunkach roztwór jest niebieski. Mieszanka litmu ma numer CAS 1393-92-6 i zawiera od 10 do 15 różnych barwników. Większość składników chemicznych litmu prawdopodobnie będzie taka sama, jak w związanej z nimi mieszaninie znana jako orceina, ale w różnych proporcjach. W przeciwieństwie do orceina, główny składnik lakmusu ma średnią masę cząsteczkową 3300. Wskaźniki kwasoodporności na litmusie zawdzięczają swoje właściwości chromoforowi 7-hydroksyfenoksazonu. Niektóre frakcje litmu podano konkretne nazwy, w tym erytrolityn, azolitmin, spaniolitmin, leukotrcein i leukazolitmin.
