Frente al resultado, el alumno se qued\u00f3 pensativo, con gesto muy serio.<\/p>\n<h3>\u00bfPor qu\u00e9 cambia el color de la llama?<\/h3>\n<p>La prueba de la llama funciona porque los \u00e1tomos del metal reciben el calor del fuego. Cuando los electrones de un \u00e1tomo se calientan, saltan a un estado de mayor energ\u00eda que lo habitual. Pero ese estado no dura mucho: al volver a su posici\u00f3n original, el electr\u00f3n libera la energ\u00eda sobrante en forma de luz.<\/p>\n<p>El color de esa luz es propio de cada elemento. Por eso, con solo mirar el color de la llama, podemos deducir qu\u00e9 elementos hay presentes. Estos son los principales:<\/p>\n<p>\u30fbLitio: rojo<br \/>\n\u30fbSodio: amarillo<br \/>\n\u30fbPotasio: violeta rojizo<br \/>\n\u30fbCalcio: rojo anaranjado<br \/>\n\u30fbBario: verde amarillento<br \/>\n\u30fbCobre: azul verdoso<\/p>\n<p>Los colores de los fuegos artificiales tambi\u00e9n se basan en este mecanismo. Ese azul verdoso se consigue con compuestos de cobre. Lo que ocurre sobre una humilde esp\u00e1tula del laboratorio es el mismo principio que ilumina el cielo nocturno con enormes fuegos artificiales. \u00bfNo te emociona pensarlo?<\/p>\n<h3>\u00bfBasta el color para decir \u00abes cobre\u00bb?<\/h3>\n<p>Vamos a dar un paso m\u00e1s. Que la llama sea verde, \u00bfnos permite afirmar sin m\u00e1s que es cobre?<\/p>\n<p>Resulta que el bario tambi\u00e9n produce una llama verde amarillenta, as\u00ed que a veces es dif\u00edcil distinguirlos solo por el color. Adem\u00e1s, aunque los libros de texto dicen que la llama del cobre es azul verdosa, seg\u00fan qui\u00e9n la mire y en qu\u00e9 condiciones puede parecer m\u00e1s azulada o m\u00e1s verdosa. Tambi\u00e9n se sabe que, al calentar compuestos de cobre que contienen cloro, la llama se ve m\u00e1s azulada. Como esta sustancia sali\u00f3 de una disoluci\u00f3n de cloruro de cobre, es posible que en la superficie quedaran restos con cloro.<\/p>\n<p>Y hay otra cosa: la prueba de la llama solo nos dice que hay un elemento, el cobre. De ah\u00ed a afirmar que se trata de \u00abcobre met\u00e1lico\u00bb hay un trecho que el color de la llama, por s\u00ed solo, no cubre.<\/p>\n<p>Por eso fue un gran acierto que el alumno combinara el \u00abbrillo met\u00e1lico\u00bb con el \u00abcolor de la llama\u00bb. Cuantas m\u00e1s pruebas se acumulan, m\u00e1s s\u00f3lida es la conclusi\u00f3n. Si queremos asegurarnos todav\u00eda m\u00e1s, podemos probar con m\u00e9todos como estos:<\/p>\n<p>\u30fbFrotarlo con papel de lija y ver si aparece un brillo rojizo<br \/>\n\u30fbComprobar si conduce la electricidad<br \/>\n\u30fbGolpearlo y ver si se aplasta sin romperse (es decir, si es maleable)<\/p>\n<p>Cuantas m\u00e1s formas de comprobarlo encontremos, m\u00e1s fuerte ser\u00e1 la hip\u00f3tesis de que \u00abes cobre\u00bb.<\/p>\n<h3>De un experimento a la siguiente pregunta<\/h3>\n<p>Este experimento acab\u00f3 convirti\u00e9ndose en una investigaci\u00f3n del tipo \u00abcomprobar con otro experimento lo que obtuvimos en la electr\u00f3lisis\u00bb. Tomar el resultado de un experimento y verificarlo con otro m\u00e9todo: as\u00ed es, exactamente, como avanza la ciencia.<\/p>\n<p>Lo pr\u00f3ximo podr\u00eda ser probar la llama con otros metales y comparar sus colores. Solo de imaginar qu\u00e9 luces nos mostrar\u00e1n en el fuego los metales que nos rodean, ya dan ganas de empezar, \u00bfverdad?<\/p>\n<h3>Contacto y solicitudes<\/h3>\n<p>\u00a1Para acercar a todos la magia y la diversi\u00f3n de la ciencia!
