Cada d\u00eda es un nuevo experimento.<\/strong><\/span><\/p>\n<p>Suaves, brillantes y con un aspecto sorprendentemente real. Unas peque\u00f1as esferas que parecen aut\u00e9nticas huevas de salm\u00f3n nacen una tras otra a partir de unas simples gotas de una disoluci\u00f3n. En esta ocasi\u00f3n aprendimos este fascinante experimento durante una actividad de intercambio con el club de ciencias de la Escuela Secundaria Femenina Kyoritsu. Lo m\u00e1s interesante es que estas &#8220;huevas artificiales&#8221; esconden uno de los fen\u00f3menos m\u00e1s importantes de la qu\u00edmica: la uni\u00f3n entre iones.

En esta ocasi\u00f3n visitamos la Escuela Secundaria Femenina Kyoritsu y volvimos con much\u00edsimas ideas nuevas.

La respuesta est\u00e1 en un fen\u00f3meno qu\u00edmico muy elegante: la <b>uni\u00f3n entre iones<\/b>.<\/p>\n<p>El alginato de sodio es un polisac\u00e1rido natural obtenido de <b>algas pardas<\/b>, como el kombu o el wakame. Sus mol\u00e9culas tienen forma de largas cadenas, y a lo largo de ellas existen numerosos grupos con carga el\u00e9ctrica negativa. Mientras estas cadenas permanecen separadas y flotando libremente en el agua, el conjunto sigue comport\u00e1ndose como un l\u00edquido.<\/p>\n<p>Sin embargo, al a\u00f1adir la disoluci\u00f3n de cloruro de calcio, todo cambia. Al disolverse, el cloruro de calcio libera <b>iones calcio (Ca\u00b2\u207a)<\/b>, que poseen dos cargas positivas. Estos iones act\u00faan como peque\u00f1os puentes: se unen a los grupos negativos de dos cadenas distintas de alginato al mismo tiempo, enlaz\u00e1ndolas entre s\u00ed. Poco a poco se forma una enorme red tridimensional en la que miles de cadenas quedan conectadas, creando una estructura s\u00f3lida y flexible.<\/p>\n<p>Este mecanismo recibe el nombre de <b>modelo de la caja de huevos<\/b> o &#8220;Egg-Box Model&#8221;. El nombre proviene de la semejanza con una huevera: igual que cada huevo encaja perfectamente en su compartimento, los iones calcio encajan entre las cadenas de alginato y las mantienen unidas de forma muy estable.<\/p>\n<p>Adem\u00e1s, esta reacci\u00f3n comienza en la <b>superficie de la gota y avanza r\u00e1pidamente hacia el interior<\/b>. Gracias a ello, cada gota conserva su forma esf\u00e9rica mientras su exterior se gelifica casi al instante. Ese es el secreto que hace que estas bolitas tengan un aspecto tan parecido al de las aut\u00e9nticas huevas de salm\u00f3n.<\/p>\n<h3>Consultas y colaboraciones<\/h3>\n<p>\u00a1Quiero acercar la ciencia a todo el mundo!
