Searching chemicals in Nature?


Hey guys, Im in croatia for 2 weeks (next to the sea if thats important) and I wanted to search some chemicals and stuff like that in nature. Do you know any special/cool chemicals that you can find here?

I think that that would be a great idea. Do some reasearch on local floura and U2U me. In Alaska, I have plenty of opportunities to do something similar but still have not had the chance yet.

Ok so, I did some research. When I google local floura I just get some flower shops and when I google U2U me I get gay porn...(not a joke)

I just realized that its a function on that forum haha

If use of chlorophyll in similar reactions is really practical or efficient is another story, though the concept is really appealing IMO!

I read that seaweed (especially the brown type) has recoverable quantities of iodine.
If this ia a rare trip to the sea then it may be worthwhile researching seaweed/kelp type before you go ?

Maybe seashells as a source of calcium carbonate ?

A litre of seawater for future reference or analysis ?

A bucket of sand for later cleaning to be used in a heating sand bath ?

A piece of driftwood to carve into a test tube stand or something ?

A collection of stones and rocks to later identify ?

Extraciting iodide from seaweed sounds interesting. Gonna try that out.

You could use mindat.org to search for minerals in the area, but I doubt there is anything interesting near the sea.

On the other hand, I'm sure you can buy interesting reagents there which aren't easily available in your country, but transporting them might be a hassle unless you go by train or by car and you live in another EU state.

Thanks! I found out that you can find Barite(barium sulfate) here.

I was going to suggest minerals, too. Minerals can be a good source of decently pure reagents, and if they're too pretty to grind up for science you can still put them on display! I found some very nice barite crystals at Pelican Beach, California on a business trip a while back.

User Peach here on the forum tried iodine extraction from seaweed several years ago, and it's not an easy task. You need a LOT of seaweed. Drying that much seaweed out in the sun doesn't smell great, either. I don't mean to discourage you, just make sure you research the process and understand what you're getting into before you commit!

Seawater is a cool idea. I gathered some local seawater and ended up with lots of nice cubical salt crystals. My plan was to analyze the salt content of the water, and find out what components it is made of. Not sure how I'm going to do that, but hey the crystals are nice looking :)

going to search some barite tomorrow. Do you know anything I can make with it?

Barium sulfate is going to be very difficult to change into anything else; it's highly insoluble, and quite happy the way it is. It's so insoluble, that even though barium is rather toxic they let you drink a suspension of it as a 'barium meal' in order to x-ray your digestive system. Trying to 'crack' the compound to make other ones is probably very difficult. But someone else may know more. Personally, I'd just keep the crystals!

If you originally live far away from any sea then collect a few buckets of sea water. Then dry the water into seasalt and probably separate the ionic components into pure compounds.

You can pick up seashells for the calcium carbonate. Get the whitest ones you can find.

Ok - Not chemistry as such (although there is chemistry in the way they are formed), but I think the coast there might be good for fossil hunting. There were fossil lizards and fish found along 'the coast' but I don't know which specific areas have the right geology... might be worth researching? Enjoy the trip.
