El contacte de la closca de l’ou, formada per carbonat de calci, reacciona amb el vinagre (\u00e0cid ac\u00e8tic)<\/div>\n
i la reacci\u00f3 de l’\u00e0cid amb el carbonat produeix el CO2, s\u00f3n les bombolletes que veiem, i altres ions que queden dissolts en l’aigua.<\/div>\n

Tamb\u00e8 veurem que l’ou s’ha fet mes gran.<\/div>\n
Aix\u00f2 \u00e9s degut a que la membrana semipermeable (aquella mena de tela que envolta la closca), deixa passar l’aigua amb l’\u00e0cid dissolt ja que la concentraci\u00f3 de sals a l’interior de l’ou \u00e9s major que a fora. Aix\u00f2 s’anomena \u00f2smosi.<\/div>\n
