You can use Sodium Thiosulfate to clean Silver. Paul What happens if you dilute acetic acid ? So 100ml measuring cylinder, put 10ml of acetic acid and 90ml of water (probably distilled) you then get a 10% solution. Would that make a difference, same would go for Citric acid, which as that can be bought in powder solution you could perhaps make known molar concentrations. Paul

Thanks, this makes more sense now, so the antibiotics in this case would kill any, I guess, dormant virus cells, before they can either move elsewhere or be transmitted to others.

There is current an outbreak of Meningitis B in Kent, United Kingdom, According to the BBC the students are being given vaccines and also preventitive anti biotics. I may be wrong here, but I thought anti biotics are used to treat infections, and not as a preventitive measure (which it what vaccines are for), Am I right here or just not understanding something. Thanks Paul

Thanks for this, if nothing else it confirms there is no right or wrong way as there are multiple conventions, I know things change over time, some are agreed changes, simple things like spelling Sulphur as Sulfur for example Does all the different group conventions make study more challenging or would a university / exam board use one convention.?

I have asked this on Mastodon, as it was related to another post I made there, but I thought I would ask here too Group 4 elements on the @compoundchem@mstdn.social infographic Carbon, Silicon etc, https://www.compoundchem.com/2013/12/29/group-4/ Whereas Wikipedia https://en.wikipedia.org/wiki/Group_4_element Suggests group 4 is Titanium, Zirconium, Most periodic tables are group 1,2 on the left, then there is a jump over the transition to group 3, Boron, Aluminum, Transition element groups are numbered IIIB, IVB (which wikipedia lists as group 4) 2nd group of the transition elements. So which is correct here, or does it depend on the periodic table you are looking at? Paul

This lecture is scheduled for the 28th Feb, but looks interesting s I am sharing here. I have also asked on Mastodon if a recording will be available. AllEventsAstronomy vs The billionaire space race

ScienceDailySchrödinger’s color theory finally completed after 100 yearsA century after Erwin Schrödinger sketched out a bold vision for how we perceive color, scientists have finally filled in the missing pieces. A Los Alamos team used advanced geometry to show that hue,So if we have software that recognizes colour, does this mean that software would need updating to allow for any changes to ideas on how we perceive colour?

I read about this on Mastodon, (I think) sounds pretty cool. Hopefully extend the life of the mission.

I agree with not using AI for study, a while back I found two posts on Mastodon regarding this. So from what I remember from these: 1 A teacher / professor provided access to AI, students were given a question then asked to explain what was wrong with the AI answer 2. A teacher / professor, required students to, of course fully cite their document including if they used AI, I got the impression from the post that the students found this created far more work than needed so just handed in their essay having undertaken the reqiired work / study / reading to produce it. Asking AI for an answer to a question is fine, getting access to all sources of information is probably a lot harder, as each source then needs to be checked, cross referenced etc. On the other side of this the Overleaf LaTeX editor now has integrated AI to help find and fix errors in your code. As this deals with the actual formatting of the document, and not the document content, would this be a different use case?

Thanks, I will take a look.

I was thinking, so there is a general space for Q&A. Paul

Ah y ea, this is fine.

I agree, a good science practical can be life changing and inspirational. Even good demonstrations can do that. I did start off with my own chemistry set from about 10. l am not sure what grade 8 is but I am guessing it is around 12/13 If you don't want to put the effort in, perhaps university is not the place for you. I don't want that to sound elitist but why is it that those who want to work hard, l study hard and learn are at a disadvantage over others who don't.

Happy to help too, but agree with the advice above, do some of your own research / reading then ask specific questions here.

Would it be possible to have a deficated LaTeX section please, this could then cover Maths, Physics, Chemistry , writing all one place. Paul
