Aquest curs a cinqu\u00e8 hem fet diversos experiments amb la barreja de vinagre i bicarbonat. Hem vist reaccions que ens han sorpr\u00e8s, per\u00f2 aquest trimestre hem volgut profunditzar una mica m\u00e9s. Qu\u00e8 era ben b\u00e9 el que va passar quan van fer les erupcions volc\u00e0niques? Qu\u00e8 passa realment quan barregem vinagre i bicarbonat?<\/p>\n

Hem seguit experimentant i aquest cop \u00a0hem utilitzat ampolles i globus per veure que provoca la barreja. Hem parlat del que s\u00f3n les reaccions qu\u00edmiques i hem fet hip\u00f2tesis sobre el que passaria i perqu\u00e8.<\/p>\n

Despr\u00e9s de comprovar-ho,vam verificar la nostra hip\u00f2tesi. Realment quan f\u00e8iem la reacci\u00f3 qu\u00edmica s\u2019inflaven els globus! I vam descobrir que aix\u00f2 passava perqu\u00e8 la reacci\u00f3 generava molt di\u00f2xid de carboni.<\/p>\n

Per tant si ho voleu fer a casa us ho expliquem:<\/p>\n

    \n
  1. Agafeu una ampolla petita i buida.<\/li>\n
  2. Ompliu-la amb dos o tres dits de vinagre.<\/li>\n
  3. Agafeu un globus i tireu-li una cullerada de bicarbonat a dins.<\/li>\n
  4. Col\u00b7loqueu el globus en el coll de l\u2019ampolla i feu que caigui de cop tot el bicarbonat a dins!<\/li>\n<\/ol>\n

    Per\u00f2 vigileu que a vegades pot sortir tot volant!<\/p>\n
