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!

This is definitely one of my favorite compounds, it’s called Copper(II) Nitrate (Cu(NO₃)₂).

As you can see, it is a really beautiful compound because of the color of its deep-blue crystals.It is widely used in labs, it converts to copper(II) oxide, which is used as catalyst for a variety of processes in organic chemistry. Its solutions are used in textiles and polishing agents for other metals.

Chemical reaction between copper (the coil) and silver nitrate dissolved in water. The silver reacts with the copper coil and grows crystals around it. The reaction is instantaneous and very pretty. The blue color of the water is a result of the copper nitrate released in the reaction.

Niobium has physical and chemical properties similar to those of the element tantalum, and the two are therefore difficult to distinguish.

Brazil is the leading producer of niobium and ferroniobium, an alloy of niobium and iron. Niobium is used mostly in alloys, the largest part in special steel such as that used in gas pipelines. Although alloys contain only a maximum of 0.1%, that small percentage of niobium improves the strength of the steel. The temperature stability of niobium-containing superalloys is important for its use in jet and rocket engines. Niobium is used in various superconducting materials

DMT

N,N-Dimethyltryptamine is a psychedelic compound.^[DMT occurs in trace amounts in mammals, including humans, where it putatively functions as a trace amineneurotransmitter/neuromodulator.

When ingested, DMT acts as a psychedelic drug. Depending on the dose and method of administration, its subjective effects can range from short-lived milder psychedelic states to powerful immersive experiences; these are often described as a total loss of connection to conventional reality with the encounter of ineffable spiritual/alien realms.

archenland — Sun, 10 Mar 2013 19:05:07 -0700

Methyl orange is a pH indicator frequently used in titrations. It is often used in titrations because of its clear and distinct colour change. Because it changes colour at the pH of a mid-strength acid, it is usually used in titrations for acids. Unlike a universal indicator, methyl orange does not have a full spectrum of colour change, but has a sharper end point.
