L’alumnat de 4t de l’itinerari cient\u00edfic han treballat la part experimental del Projecte de Recerca, per altra banda els de 3r… no s’han estat de res, tampoc! Imatges aqu\u00ed.<\/a><\/p>\n

Per aprofundir en el m\u00f3n de les fant\u00e0stiques reaccions qu\u00edmiques han fet diferents experiments al laboratori i al pati de l’institut.<\/p>\n

Sabeu que hi ha una reacci\u00f3 que se l’anomena pasta de dents d’elefant? Doncs resulta que surt de la descomposici\u00f3 de l’aigua oxigenada amb un catalitzador. Molt vist\u00f3s i conegut al m\u00f3n youtuber! Tamb\u00e9 hem propulsat un coet amb etanol aprofitant la reacci\u00f3 de combusti\u00f3 i hem fet indicadors de pH amb materials tan casolans com l’aigua de bullir col llombarda, comprovant aix\u00ed la reacci\u00f3 de neutralitzaci\u00f3.\u00a0 Per \u00faltim, hem vist l’oxidaci\u00f3 en medi aqu\u00f3s d’uns claus de taller en diferents condicions per veure les reaccions de s\u00edntesi i redox.<\/p>\n

Si en voleu m\u00e9s detalls, podeu investigar pel vostre compte i descobrir… qu\u00e8 \u00e9s la pluja d’or relacionada amb la cristal\u00b7litzaci\u00f3 del iodur de plom (II), i la floculaci\u00f3 de la mat\u00e8ria org\u00e0nica d’una aigua residual? Sabeu qu\u00e8 passa quan s’entrecreua el pol\u00edmer PVA amb els polifosfats d’un detergent?<\/p>\n

Si ho trobeu, ja ens ho explicareu!<\/p>\n<\/div>\n
