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?

It decomposed.

Cu(OH)2 + heat (185°C) → CuO

When heated, Cu(OH)2 liberates its hydrogens and CuO is formed.

Some Cu(OH)2!

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!
