  • @Xhaosz Balance reaction through that shake stands a new balance a that the material favored the blue is zb in gases changes the balance the pressure increased becomes on the side the less gaseous molecules possess.

  • Inside the glass tube is Methylene blue (an indicator), glucose, and sodium hydroxide. When the flask is shaken, the glucose in the water is oxidized by the oxygen in the water(must be in an alkaline environment), to form gluconic acid. Gluconic acid forms sodium gluconate in the presence of sodium hydroxide, and in the process methylene blue is reduced, tu rning colorless. Methylene blue is blue when oxidized, clear when reduced

  • If U dont like waisting time then y are u on YouTube: The Time Killer!

  • Same thing with rubbing alcohol and food coloring it takes the color away

  • Hier wird eine basische Glucose-Lösung mit Methylenblau versetzt. Die Glucose reduziert das Methylenblau und setzt es zur entsprechenden Leuco-Base um. Durch das Schütteln gelangt wieder Luftsauerstoff in die Lösung und oxidiert die Leucobase wieder zum Methylenblau, welches durch die Glucose wieder reduziert werden kann.

    Sehr schöner Versuch!
