This Week in Chemistry – Slowing Sodium’s Reaction With Water, and Titan’s Methane-Filled Canyons

16-08-20 This Week in Chemistry

Here’s the weekly summary of both new chemistry research and studies that have been in the news. This week features news on slowing down the reaction between sodium metal and water so that the individual stages of the reaction can be seen, insights into the structural origin of iodine’s colour change with starch, and more. As always, links to further articles and original research papers are provided below, as well as further studies of interest not included in the graphic.

Note: links to studies behind a journal paywall are indicated with (£). Studies without this symbol are open access, and can be accessed and read for free.

Other Stories This Week

I’m on holiday for the next few weeks, and while I didn’t want to stop creating graphics completely, I am planning on taking it a little easier! For that reason, there will be no additional stories for This Week in Chemistry for the next few weeks. Normal service will resume in September.
