bday gee as high test lye 😭

This Gerard Way is high test lye aka sodium hydroxide (NaOH)!

In his concentrated form he can be corrosive!

Turning desalination waste into a useful resource

The rapidly growing desalination industry produces water for drinking and for agriculture in the world's arid coastal regions. But it leaves behind as a waste product a lot of highly concentrated brine, which is usually disposed of by dumping it back into the sea, a process that requires costly pumping systems and that must be managed carefully to prevent damage to marine ecosystems. Now, engineers at MIT say they have found a better way.

In a new study, they show that through a fairly simple process the waste material can be converted into useful chemicals—including ones that can make the desalination process itself more efficient.

The approach can be used to produce sodium hydroxide, among other products. Otherwise known as caustic soda, sodium hydroxide can be used to pretreat seawater going into the desalination plant. This changes the acidity of the water, which helps to prevent fouling of the membranes used to filter out the salty water—a major cause of interruptions and failures in typical reverse osmosis desalination plants.

The concept is described today in the journal Nature Catalysis and in two other papers by MIT research scientist Amit Kumar, professor of mechanical engineering John. H. Lienhard V, and several others. Lienhard is the Jameel Professor of Water and Food and the director of the Abdul Latif Jameel Water and Food Systems Lab.

Today on my Drug Chemistry lab I’ve had to detect unknown chemical compound (drug). First I was testing sulibility in water and methanol and next I added sodium hydroxide (NaOH) and I was heating it on the burner. My clear solution changed color to orange. I’ve already known that I had chloramphenicol in my test-tube, but I decided to confirm it by test to Cl- ion with AgNO₃ and I was observing white sludge darkens on expousure to light.
