  • good ol' tollens

  • Is your silver solution the same as the "Tollens' Reagent" The A-Level AQA syllabus keeps insisting on, or has this been done differently?

  • It's shiny and, therefore, reflective. Moreover, the vacuum space between the inside and outside of the flask will prevent the transmission of heat in either direction.

  • It's a reflective surface and will reflect the heat transmitted by any hot liquid liquid on the inside of the vacuum flask. Conversely it will reflect the heat of the air on the outside of the flask and help to keep liquids inside the flask cool.

  • This doesn't make sense. Out of date ammonia wouldn't have much ammonia in it. Most of it would be lost to the atmosphere over time since ammonia is a gas and the ammonia solution is merely the gas dissolved in water. I think something else must have been the source of the smell.

  • Yup, similar to the silver mirror test for aldheydes....doesn't take that long at all to see the mirror.

  • His Royal Stigness

  • I understand that mirrors can be made with aluminum too. Does anyone know the chemical process for making an aluminum mirror. Replacing silver nitrate with aluminum nitrate seems way too easy.

  • evry time i watch one of their vids i get either hyper or just happy i just enjoy their success in chemical reactions

  • 4:13 :D :D Perfect
