Preparation of dichromate from Cr(III) waste video
Guys I finally finished editing the video of recycling Cr(III) waste back to dichromate.
I hope I made the video easy to follow. If anyone is interested in the process here's the link:

Thanks to all the suggestions on the forum for helping produce a method for this reaction.

The colour of your final solution suggests you've got a chromate-dichromate mix. I would check the pH of the solution before crystallization.

You wrote on start of the video that Cr(III) and Cr(IV) is carcinogenic. Cr(III) isn't carcinogenic and I suppose that Cr(IV) is mistake and you mean
Cr(VI).

the music made it un watchable. I'd recommend longer sub titles with a bit more info and just let nature lab sounds fill the track.
or write a script, then narrate on a separate sound channel then overlay where appropriate.

About 43 seconds: buy a funnel.
Also, don't forget to wash the NaOH carefully out of the separating funnel (or it ****s the tap)
