Home Chemistry 6 – Reactions of metals with Citric Acid
So while I wait for delivery of some more indicator paper. I am going to take a look at how Magnesium reacts with Citric Acid.
Firstly as indicated in a Previous post it is important to ensure the Magnesium metal is clean and free of tarnish. This will aid the reaction by exposing a greater surface area of the metal.
I will be using the same equipment as before,
As well as Citric Acid, which is shown here along side Bicarbonate of soda.
I decided to use a conical flash instead of a test tube and this makde it a little easier to observe the reaction.
I added some Citric Acid powder to the flask, added about 50ml water to dissolve the acid then added one piece of Magnesium ribbon, approx 1” long to the solution.
Took a few mins to get going, once the remaining tarnish had gone, the reaction speeded up.

British Science Week
British Science week 2023 takes place between the 10th and 19th March 2023.
The March Paignton Library STEM Group meeting takes place on the 11th March so we can do more of the same activities, I am still trying to get round to doing some Chemistry related activities at the event.

Home Chemistry 5 – Electrochemical Series
As it was suggested revise the Electrochemical on Science Forums. I am including a video from youtube on this topic.

Astronomers want a more powerful telescope
This sounds like a really good development, and shows how exciting things are going to get. I have replied and mentioned the Nancy Grace Telescope (due later this decade) and asked about the difference between a space telescope and one placed on the dark side of the moon.
This is another reason to STUDY STEM, and include maths, computing within that so we have people to help analyse all the data being sent back, and we also need people to design, build everything around this.
Because of the fantastic success of #JWST, now astronomers want even more powerful gear up in space.
They are planning the Habitable Worlds Observatory that would be even bigger and make detecting life on other #Earth-like #planets reality.
The telescope will also be perched at L2. Unlike JWST, it will be designed for robotic servicing and upgrades, which could enable it to operate for decades.
