CE ÎNSEAMNĂ LITMUS TEST ÎN ENGLEZĂ?
Turnesol
Litmus este un amestec solubil în apă de diferite coloranți extrași din licheni, în special Roccella tinctoria. Acesta este adesea absorbit pe hârtie de filtru pentru a produce una dintre cele mai vechi forme de indicator de pH, folosit pentru a testa materialele pentru aciditate. Hârtia albastră se transformă în roșu în condiții acide, iar hârtia roșie de litmus devine albastră în condiții de bază, schimbarea culorii având loc în intervalul de pH 4,5-8,3 la 25 ° C. Hârtia neutră de litmus este violet. De asemenea, Litmus poate fi preparat ca o soluție apoasă care funcționează în mod similar. În condiții acide, soluția este roșie, iar în condiții de bază soluția este albastră. Amestecul litmus are numărul CAS 1393-92-6 și conține 10 până la 15 coloranți diferiți. Majoritatea componentelor chimice ale litusului sunt probabil aceleași cu cele ale amestecului asociat cunoscut sub numele de orceină, dar în proporții diferite. Spre deosebire de orceină, principalul constituent al litusului are o greutate moleculară medie de 3300. Indicatorii bazei acide pe litmus își datorează proprietățile lor unui cromofor de 7-hidroxifenoxazonă. Unele fracțiuni de litmus au primit nume specifice, incluzând eritrolitmină, azolitmină, spaniolitmină, leucoorceină și leucazolitmină.
