Aprofitant que aquests dies ens acompanya en Fabian, un mestre que fa pr\u00e0ctiques a la nostra escola, els alumnes de 5\u00e8 hem fet un taller per tal de determinar que \u00e9s el pH de les subst\u00e0ncies. <\/b><\/span><\/span><\/p>\n

Hem descobert que n\u2019hi han de diferents tipus segons el seu pH, per exemple trobem les que s\u00f3n \u00e0cides com el vinagre o el suc de llimona, d\u2019altres que s\u00f3n neutres com l’aigua o la llet, i finalment les que s\u00f3n b\u00e0siques com el bicarbonat.<\/b><\/span><\/span><\/p>\n

Vam fer dos experiments diferents per determinar el pH. El primer consistia en agafar unes tires de paper comercials que es poden comprar (paper indicador de pH). Aquestes en submergir-les en la subst\u00e0ncia que voliem analitzar, es tornava d’un color diferent segons el seu pH. <\/b><\/span><\/span><\/p>\n

El segon experiment, consistia en utilitzar el nostre propi indicador elaborat a partir de suc de col lombarda. Semblava m\u00e0gia el fet de veure com diferents productes (llet, vinagre, aigua, bicarbonat, etc.) anaven canviant de color quan se\u2019ls afegia el suc de col lombarda. Aix\u00ed, els productes \u00e0cids, agafaven color vermell, els neutres groc i les bases blau.<\/b><\/span><\/span><\/p>\n

Va ser molt interessant i vam aprendre coses \u00fatils per la nostra vida di\u00e0ria! <\/b><\/span><\/span><\/p>\n

GR\u00c0CIES FABIAN PER AQUESTA ACTIVITAT!!!<\/b><\/span><\/span><\/p>\n
