ELABORACIÓN DE UN COLIRIO OFTALMOLÓGICO

ELABORACIÓN DE UN COLIRIO OFTALMOLÓGICO

La aplicación de lo aprendido en beneficio de la humanidad es algo de bastante importancia para el mundo de la ciencia, especialmente para la química. Si los estudiantes no experimentan en el laboratorio y no aplican lo aprendido en clases, lamentablemente lo olvidaran y no habrá una experiencia satisfactoria de aprendizaje. El mundo real de la química, se vive en el laboratorio, mediante las observaciones, mediciones, hipótesis, interpretaciones, entre otros. Por tal razón, en el laboratorio en casa de hoy, te dejamos una opción sencilla que te servirá para llevar a cabo tu proyecto de química y no fallar en el intento.

Reactivos a utilizar
  • 0,05g de tetraoxosulfato (VI) de zinc
  • 2,5g de ácido bórico
  • 100ml de agua destilada

 

Procedimiento
  • En un vaso de precipitados o en algún otro envase de vidrio, añade 100ml de agua destilada.
  • Agrega 2,5g de ácido bórico y 0,05g de tetraoxosulfato (VI) de zinc.
  • Finalmente, agita hasta que la solución quede completamente homogénea, es decir, hasta que el ácido bórico y el tetraoxosulfato (VI) de zinc se disuelvan completamente.
  • Envasa en un recipiente que tenga cuentagotas.
  • Usa una gota en cada ojo para refrescar la vista.

  1. Hey there! Quick question that’s completely off topic. Do you know how to make your site mobile friendly? My website looks weird when viewing from my iphone4. I’m trying to find a theme or plugin that might be able to correct this problem. If you have any recommendations, please share. Thank you!
