Estem saturats!, comentaven alguns alumnes de 3r, durant els dies d’ex\u00e0mens… I va ser llavors quan, encaixant la frase amb la mat\u00e8ria de qu\u00edmica, havia aparegut una situaci\u00f3 ideal per parlar de qu\u00e8 era la concentraci\u00f3 d’una dissoluci\u00f3. Aquesta analogia els va portar a entendre un seguit de conceptes, a aplicar algunes f\u00f3rmules per fer c\u00e0lculs, a interpretar gr\u00e0fiques i a fer una pr\u00e0ctica al laboratori per preparar una dissoluci\u00f3. I, d’aquesta manera, fer mem\u00f2ria d’accions que havien de dur a terme o materials que havien d’utilitzar. Estaven saturats, per\u00f2 una bona organitzaci\u00f3 de treball faria que no precipitessin!<\/p>\n

Avan\u00e7ar el tema va fer apar\u00e8ixer una altra pregunta. Potser us ha passat que, despr\u00e9s d’un sopar de celebraci\u00f3, noteu una certa acidesa a l’est\u00f3mac… Qu\u00e8 es\u00a0pot fer per amortir aquesta sensaci\u00f3? Caldria, tal i com van aprendre, neutralitzar l’\u00e0cid. Ho van comprovar a trav\u00e9s d’una altra pr\u00e0ctica, on es va veure que barrejant un \u00e0cid amb una base s’aconseguia generar di\u00f2xid de carboni, que omplia un globus. I no nom\u00e9s aix\u00f2, sin\u00f3 que permetia comprovar la llei de conservaci\u00f3 de la massa de Lavoisier.<\/p>\n

Dues situacions quotidianes, doncs, que van demostrar la proximitat i utilitat de la qu\u00edmica!<\/p>\n\n\n\n
