#2 is potasium dichromate,#4 is nickel sulfate,#5 is copper sulfate,#6 is tetraamine copper nitrate #7 was scooped off the back yard?:D

[Edited on 12-25-2014 by cyanureeves] #7 is copper acetylide.on magnification it looks very pretty actually.

#2 is a dichromate, ammonium actually, #4 isn't a nickel salt, #5 is copper sulfate, #6 isn't tetraamine copper nitrate, #7 isn't copper acetylide. The purple is a complex between an inorganic and organic compound.

#3 could be a chromate salt, or possibly a ferric salt. #7 is an ethylenediamine nickel complex.

The purple isn't an indicator, it's a complex. #1 is an organic indicator, #4 is CuCl4 2- Huh, the superscripts aren't working.

#1 is probably phenolphtaleine
#2/3/5 were easy to guess :p
#4 I learned something, didn't know that one :D
#6 I got no idea, i'm gonna learn something again !
#7 could be Salicylic acid /iron complex (maybe with FeCl3) ... or maybe a dilute iodine/starch complex but yeah.. I definitely think it's a salicylic acid/iron complex

Yep, #1 is phenolphthalein, #7 is a dilute salicylic acid/ferric chloride complex, #6 is dilute methylene blue.

This is pretty!



Rapopart’s Rules for critical commentary:

1. Attempt to re-express your target’s position so clearly, vividly and fairly that your target says: “Thanks, I wish I’d thought of putting it that way.”
2. List any points of agreement (especially if they are not matters of general or widespread agreement).
3. Mention anything you have learned from your target.
4. Only then are you permitted to say so much as a word of rebuttal or criticism.

Anatol Rapoport was a Russian-born American mathematical psychologist (1911-2007).

It's called different things in various cultures: "girondola", "table rocket", "flying crown", "tourbilion", "UFO"...

Search for girondola on Youtube, lots of videos in all sizes and many different configurations. But THAT one is the biggest I've ever seen!

Crystals of tris(ethylenediamine)nickel(II) oxalate. I was trying to make a bis(en) complex with a coordinated oxalate, but refluxing was not taking off the third en ligand, nor was heating the solid to over 300 oC.
