Până în anii 1950, băutura răcoritoare de lămâie-lime 7-Up conţinea citrat de litiu.
Acest compus chimic este, probabil, cel mai bine cunoscut pentru utilizarea sa în medicamentele psihiatrice. Acesta are rolul de stabilizator a stării de spirit pentru persoanele care suferă de tulburare bipolară.
Desigur, în zilele noastre, 7-Up este lipsit de substanţe psihoactive. Cu toate acestea, cei de la canalul de YouTube Periodic Video s-au întrebat ce s-ar întâmpla dacă adăugi elementul chimic litiu într-un lichid de 7- Up modern.
Rezultatul este o reacţie chimică neaşteptată care poate fi urmărită în video-ul de mai jos, unde Sir Martyn Poliakoff vă ghidează prin unele dintre cele mai bune investigaţii ştiinţifice ale sale.
