1-Objetivo
Conseguir que los pigmentos del jugo expulsado por las espinacas, el alcohol y el bicarbonato cálcico asciendan por un papel de cromatografía cambiando de color según la altura a la que se sitúe el jugo en el papel.
2-Materiales
Los materiales escogidos para esta práctica son:
3-Procedimientos
3.1- Machacamos con un mortero la espinaca, y el bicarbonato cálcico añadiéndole alcohol cuando sea necesario.
3.2- Cogemos un papel de filtro y lo colocamos en un embudo situado encima de la probeta.
3.3- Cuando el jugo desprendido por los elementos anteriores esta lo suficientemente verde lo echamos a la probeta (pasando por el embudo y el papel de filtro).
3.4- De lo que sobra echamos a la placa de petri un poco (lo justo para llenar la base).
3.5- Cogemos un poco de papel de cromatografía, y esperamos hasta que suban los pigmentos que deben dar color al papel de filtro
4- Observación y recogida de resultados
Observamos que al cabo de un rato, los pigmentos de la mezcla ascienden por el papel de cromatografía variando el color entre tonos verdes, amarillos y transparentes.
5-Conclusiones
El papel de cromatografía absorbe los pigmentos de la mezcla hecha anteriormente, finalmente en el papel de cromatografía se pueden apreciar diferentes colores.
