Home Chemistry 1 – Follow up
So just posting a follow up to the experiment with a photo of the test tubes.
So we can see From this that the tube on the far left still has Zinc, the one on the Far right has Copper. The centre tube did have the Magnesium, but this is now Magnesium Acetate.
So an interesting experiment.
Testing for Acetate
For those taking a more scientific approach and who may want to test to confirm what is produced the following from Robolab may be useful.
Further reading
I have started a thread on Scienceforums to ask how to decontaminate the other metals. They may need this but it would be good practice not to simply remove from test tubes, leave to dry and put back in the original containers.
Feel free to discuss further on Mastodon. My profile is at https://qoto.org/@zleap

LibrePlanet 2023
This years Free Software Foundation conference is back in Boston as an in person conference, however talks will still be streamed online. It will run from March 18th to 19th, 2023.
This years theme is Charting the course.
I have been helping with reviewing talks for the conference, so from this I know there is a really good range of interesting talks, workshops for the event.

Young coders contest
As a few attendees are interested in this, I am sharing the information.
There is a young coders contest coming up in 2023, that runs from January to May. The video below is from the 2022 contest
You can register for this on the website
Hope to get a few schools on board with this to help support those taking part.

Home Chemistry 1 – Results
Results
An hour in to the experiment :– so 15:15 on 03/1/2023
Copper foil and zinc have produced little in the way of reaction. The Magnesium on the other hand has fully reacted with the Vinegar.
Conclusion
Other than stating the obvious, the Magnesium is clearly the more reactive with vinegar. But then Magnesium is a group 2 element, where as the others are Transition, so the properties are different anyway.
Home Chemistry 1
A few days ago I was having a look what would happen if various metallic elements were added to a beaker of Distilled White vinegar.
Using Zinc (Zn) didn't appear to do very much, however dropping Magnesium (Mg), did appear to produce a slow reaction, which seemed to result in the magnesium dissolving.
So the experiment I am going to carry out will use the following:
Equipment
- Test Tube Rack
- 3 Test tubes
Elements
- Zinc Granuals (Zn)
- Copper Foil (Cu)
- Magnesium Ribbon (Mg)
- Distilled White Vinegar
Other
- Universal indicator paper
This is not strictly needed, but will be used to test the pH of the vinegar before I start.
Method
- Part fill each test tube with White Vinegar
- Place 1 sample of each element in a test tube.
- Note Copper foil and magnesium ribbon should be cut to size.
- Place out of the way for a period of time and monitor results
Notes
Experiment started 14:13 on 03/01/2023

Bresser Microscope
I received a Bresser usb Microscope for christmas. This is a nice, compact unit capable of 50x to 1000x magnification.
USB Microscope :
The supplied software is Windows & Mac (or this can be downloaded). As I am running Debian 11.x I used Cheese which is camera software. The software works fine. As seen in the photo below.

Share to Mastodon – Firefox plugin
There is now a new plug in for Mozilla Firefox which facilitates the sharing of articles to the Federated social media network Mastodon, part of the Fediverse.
This is a really good step forward, and will really help.

Street Medic Hip Pocket Class
If you are interested in learning how to be a street medic, or at least learn enough to help people. This may be of interest.
Follow Rayne, Bookchin's fav catgirl @saladbar[email protected] on the fediverse for more information.
Clearly in the Uk we have a different system, however a good point is made about learning CPR and simple life saving, it can make all the difference until help arrives.
