L’alumnat de 4t ESO ha pogut experimentar al laboratori de Qu\u00edmica amb diverses subst\u00e0ncies per a observar les seves reaccions. Entre elles han vist: canvis de color, alliberament de gasos i l\u2019aparici\u00f3 de bombolles. Aquestes s\u00f3n algunes evid\u00e8ncies de canvis i reaccions qu\u00edmiques.<\/p>\n

Entre les pr\u00e0ctiques fetes, cal destacar la de la reacci\u00f3 d\u2019oxidaci\u00f3-reducci\u00f3 (Redox) entre el Sulfat de Coure i el Ferro, la reacci\u00f3 de neutralitzaci\u00f3 del carbonat de calci amb l\u2019\u00e0cid clorh\u00eddric per formar una sal, precipitar iodur de plom com a producte final d\u2019una reacci\u00f3 qu\u00edmica i van observar com les reaccions exot\u00e8rmiques desprenen energia en forma de calor i les endot\u00e8rmiques absorbeixen energia de l\u2019entorn en forma de calor.<\/p>\n
