/sci/ - Science & Math

YOU SHOULD BE ABLE TO SOLVE THIS EDITION

This is a thread for discussion of applied chemistry. This means mainly inorganic chemistry with things you can buy from a hardware store or eBay. Some practical uses include:
>rust removal and tool restoration
>metal plating and anodising
>precious metal refining
>circuit board etching
>solid rocket motors

Useful resources:
>sciencemadness.org
>library.sciencemadness.org
>finishing.com
>https://en.wikipedia.org/wiki/List_of_reduction_potentials
>sci-hubtw.hkvisa.net/
>https://www.webqc.org/balance.php
There’s all sorts of scientific papers and blogs and patents out there tackling individual reactions, search engines are your friend. Knowing what terms to search is often the hardest part of studying a new topic.

For books check libgen

Sources of ingredients and paraphernalia:
>ebay/aliexpress
>alibaba
>hardware stores
>farming/gardening stores
>pool stores
>local chemical suppliers (may not sell to home addresses)
Due to how quantitative this hobby is, proper measurement equipment is quite important. A good set of scales is useful, alongside graduated glassware. Strips of universal pH paper are cheap and usable, but not accurate.

>for explosives go to /fbi/

Why is the paramagnetic shielding largely determined by the HOMO-LUMO gap for most NMR active nuclei?

One is a magnetic transition, the other is an electronic transition. Why are they related?
