Cada d\u00eda es un experimento.<\/strong><\/span><\/p>\n<p>\u00bfTe costar\u00eda creer que dentro de un bol\u00edgrafo negro puede estar escondido un aut\u00e9ntico \u00abarco\u00edris\u00bb? En esta ocasi\u00f3n, me anim\u00e9 a realizar un experimento fascinante que permite comprobarlo con nuestros propios ojos: la \u00abcromatograf\u00eda en papel\u00bb. Solo necesitamos papel de filtro, agua y tinta soluble en agua. Con materiales que podemos encontrar f\u00e1cilmente en casa, podemos investigar qu\u00e9 se esconde detr\u00e1s de los colores.<\/p>\n<h3>\u00bfQu\u00e9 es la \u00abcromatograf\u00eda en papel\u00bb, el experimento que separa los colores?<\/h3>\n<p>La cromatograf\u00eda en papel es un experimento en el que se deja que la tinta soluble en agua penetre en un papel de filtro y, posteriormente, se deja que el agua la vaya extendiendo poco a poco. De esta manera, los diferentes pigmentos que forman la tinta se separan. Para este experimento utilic\u00e9 un vaso de precipitados de 50 ml, papel de filtro n.\u00ba 2 (\u03c6110 mm de di\u00e1metro) y una toalla para secar el papel. <b>Tambi\u00e9n se puede utilizar un filtro de caf\u00e9 en lugar del papel de filtro<\/b>, lo que hace que sea un experimento muy f\u00e1cil de realizar con materiales que tenemos en casa. Adem\u00e1s, grab\u00e9 todo el proceso con una c\u00e1mara en modo time-lapse para poder observar con calma c\u00f3mo iban apareciendo los cambios de color.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-39380 aligncenter\" src=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2022\/02\/IMG_6137.jpg\" alt=\"\" width=\"488\" height=\"366\" srcset=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2022\/02\/IMG_6137.jpg 1024w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2022\/02\/IMG_6137-300x225.jpg 300w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2022\/02\/IMG_6137-768x576.jpg 768w\" sizes=\"auto, (max-width: 488px) 100vw, 488px\" \/><\/p>\n<h3>Coloreamos el papel de filtro y\u2026 \u00a1comienza el experimento!<\/h3>\n<p>Primero, cortamos el papel de filtro en ocho partes iguales y dibujamos sobre ellas con rotuladores de tinta soluble en agua.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-39382 aligncenter\" src=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2022\/02\/IMG_6130.jpg\" alt=\"\" width=\"494\" height=\"371\" srcset=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2022\/02\/IMG_6130.jpg 1024w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2022\/02\/IMG_6130-300x225.jpg 300w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2022\/02\/IMG_6130-768x576.jpg 768w\" sizes=\"auto, (max-width: 494px) 100vw, 494px\" \/><\/p>\n<p>Probamos diferentes colores, como verde, azul, negro y rojo.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-39383 aligncenter\" src=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2022\/02\/IMG_6126.jpg\" alt=\"\" width=\"492\" height=\"369\" srcset=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2022\/02\/IMG_6126.jpg 1024w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2022\/02\/IMG_6126-300x225.jpg 300w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2022\/02\/IMG_6126-768x576.jpg 768w\" sizes=\"auto, (max-width: 492px) 100vw, 492px\" \/><\/p>\n<p>Colocamos los papeles en vasos de precipitados que conten\u00edan unos 8 ml de agua y observamos c\u00f3mo se iban extendiendo los colores mientras grab\u00e1bamos el proceso en time-lapse.
