Infographics on the colours of poinsettia, pomegranate and watermelon. The colours of poinsettia bracts and pomegranate are both caused by anthocyanins, while the red-pink coloration of watermelon is due to the carotenoid lycopene.

For day 2 of #ChemAdvent we look at the chemical connection between the colours of poinsettia and pomegranate – both caused by anthocyanin compounds.

These compounds also change when added to solutions of different acidity or alkalinity, giving a rainbow of colours 🌈

Many thanks to everyone who has already signed up to this (over 450+ schools).

We need a few more schools to sign up so we have a good dataset to work with.

Copper Sulfate

Wonderful crystals, dangerous blue or a 'power up' ???

We are getting an increasing number of emergency Helplines about Copper Sulfate.

Please see the latest details here : science.cleapss.org.uk

Now resolved

We are having internet/phone issues.

If you have an emergency Helpline i.e. child swallowed Copper Sulfate not I can’t log in then please call our emergency number 07871 877434

Copper Sulfate, an age old classic ?

Or a new dangerous blue issue ?

Making Copper Sulfate solution / crystals ?

Then always use a water bath to stop dangerous fumes being formed.

Please also refer to the latest Hazcards about the storage of the forming crystals as this has changed....

Infographic on the chemistry of poppies. The red colour of the common poppy is due to anthocyanin pigments. Other red poppies also contain anthocyanins but the yellow Iceland poppy and alpine poppy contain nudicaulin pigments. The opium poppy has been used in medicine for thousands of years, with the milky opium fluid which contains alkaloids such as morphine used as a painkiller. The common poppy contains different alkaloids, which only have very milld pain-killing properties.

Poppies are a symbol of remembrance on Armistice Day. Did you know that some poppies are also the source of powerful opioid painkillers?

Here is the video of the glistening crystals of lead iodide. The glistening crystals are formed during formation (as they are so thin) and by the bombardment with surrounding water molecules. #ChatChemistry, #ITeachChem @cleapss.bsky.social

We are comparing the diffusion speeds of halogens along damp starch/iodide paper. This activity is conducted in Petri dishes on the bench. The final section shows iodine result and uses 1 tiny ball of iodine.

Confusion abounds as to whether iodine sublimes or evaporates at 1 atm. In fact, it melts and flows. A little microscale triumph. See tinyurl.com/2nw2hram
