Also, I “mixed” some water and elemental sodium
I’ll upload the video in some minutes
(I really like this picture)
I got some Selenium today. I didn’t know it is a component of some aminoacids and we have it in out bodies (I find it amazing) :)
Do you guys remember last night’s post? (1st picture)
In the second picture we have the same solution but, what happened to it?
Cu(OH)2 + heat (185°C) → CuO
When heated, Cu(OH)2 liberates its hydrogens and CuO is formed.
I made this little reaction today
The pink solution is a solution of Cu+2, SO4-2, NO3- and Co(H2O)6+2
I added some NaOH and Cu(OH)2 precipitated!
