Sustainable electrolysis using light instead of wasting the battery. Copper on the cathode
#chemsky #chemchat #realtimechem #beyondbenign #iTeachChem #Chemistry
This is electrolysis using light. The 8 light cells are arranged in parallel to provide a voltage of about 3 V and a current of 65 mA. Copper chloride solution is electrolysed to give copper and chlorine Bleaching litmus, affecting starch/iodide paper, and potassium iodide solution.

For day 14 of #ChemAdvent, we've got two fruity-themed graphics.

The first is on festive flamethrowers with orange peel and limonene 🍊 🔥

The other is on nastar, Indonesian pastry-based desserts filled with spiced pineapple jam 🍍

#ChemSky 🧪
Infographic on orange peel flamethrowers, explaining how the presence of flammable D-limonene in orange peel oils makes it very flammable. The structure of D-limonene is shown and there's also a safety disclaimer. Infographic on nastar, Indonesian pastry-based desserts filled with spiced pineapple jam. The structures of some key chemical contributors to pineapple flavour and aroma are shown; these include esters, such as ethyl-2-methylbutanoate and allyl hexanoate, and furaneol, also known as pineapple ketone.

In the latest edition of #PeriodicGraphics, we take a look at the ingredients doing more than spicing up our cooking: cen.acs.org/biological-c...

#chemsky 🧪
This graphic explains four examples of chemicals in spices having effects outside cooking. The four examples include a clove compound’s ability to treat toothaches, a nutmeg compound’s ability to cause hallucinations, a licorice extract compound’s ability to raise blood pressure, and a fenugreek compound’s ability to make urine and sweat smell like maple syrup.

The gap between teacher pay and other college graduates’ pay is the highest it’s been in over four decades.

Is there a “teacher shortage,” or a shortage of jobs that treat educators with the pay, dignity, and support they deserve?

Here’s the resultant inkcap ink. Pro tip: don’t sniff it. I made this mistake and now the stench of mushroom death may never leave my nostrils 🤢

Aotearoa New Zealand launches campaign to find love for Ned, a rare & lonely left-spiralling snail.

Nearly all common garden snails have shells that coil to the right, but Ned’s shell results in reversed reproductive organs – a barrier to mating.

Yesterday, Donald Trump said that the U.S. has "too many non-working holidays."

Our so-called "pro-worker president" thinks that workers should have fewer days off.

Meanwhile, he's spending a huge chunk of his presidency (and taxpayer dollars) on the golf course.

Hello?
