El pH \u00e9s una propietat de les subst\u00e0ncies b\u00e0sica en el nostre dia a dia i per aquest motiu l’alumnat de 4t d’ESO ho est\u00e0 estudiant i experimentant des de l’assignatura de f\u00edsica i qu\u00edmica.<\/p>\n

Durant aquestes \u00faltimes setmanes, han elaborat un indicador de pH natural a partir de col llombarda i ens han fet uns magn\u00edfics v\u00eddeos en format curt per mostrar el proc\u00e9s. Despr\u00e9s han vingut al laboratori i han hagut de fer de detectius. Utilitzant l’indicador natural que han elaborat, se’ls han donat 5 tubs d’assaig amb diferents subst\u00e0ncies de les quals nom\u00e9s podien consultar el seu recipient i han hagut de descobrir quina era cadascuna a partir del seu pH, i sabeu qu\u00e8? La majoria ho han encertat!<\/p>\n

Ara ja nom\u00e9s els queda veure com aquesta propietat \u00e9s important en subst\u00e0ncies que fan servir al dia a dia, com el sab\u00f3, els aliments, els xamp\u00fas, les cremes, els productes de neteja. Han fet una gran feina.<\/p>\n
