AI Thread Summary
Understanding radical reactions and half arrow mechanisms can be challenging, but the dot and cross model offers an intuitive approach for visualizing these processes. This model helps clarify the behavior of electrons in radical reactions, making it easier to grasp the concept of one-electron mechanisms. Transitioning from two-electron mechanisms, which utilize full arrows, to one-electron mechanisms for radicals should be manageable with practice. Engaging with the dot and cross model can enhance comprehension without leading to misconceptions, provided that the learner remains aware of the differences in electron movement between the two types of mechanisms.

I'm learning about various radical reactions, the thing is I'm still getting my head around 'half arrow' mechanisms. However for some reason the dot and cross model for these types of reactions is really intuitive and works great for my understanding. Is this a dangerous path to go down, to work out half arrow mechanisms?

I've not heard of the dot and cross model, can you explain a bit? If you are comfortable with 2-electron mechanisms using arrows, you should be able to easily transition to the 1-electron version for radicals. Maybe you need some practice?
 

Thread 'Humidity of a saturated NaCl solution with anticaking additive'

I want to test a humidity sensor with one or more saturated salt solutions. The table salt that I have on hand contains one of two anticaking agents, calcium silicate or sodium aluminosilicate. Will the presence of either of these additives (or iodine for that matter) significantly affect the equilibrium humidity? I searched and all the how-to-do-it guides did not address this question. One research paper I found reported that at 1.5% w/w calcium silicate increased the deliquescent point by...

Thread 'Resists for etching Aluminium with NaOH'

I'm trying to find a cheap DIY method to etch holes of various shapes through 0.3mm Aluminium sheet using 5-10% Sodium Hydroxide. The idea is to apply a resist to the Aluminium then selectively ablate it off using a diode laser cutter and then dissolve away the Aluminium using Sodium Hydroxide. By cheap I mean resists costing say £20 in small quantities. The Internet has suggested various resists to try including... Enamel paint (only survived seconds in the NaOH!) Acrylic paint (only...
