AI Thread Summary

To calculate the ionic radius of the chloride ion in the NaCl structure with a unit cube length of 5.14 angstroms, it is essential to assume anion-anion contact. In this context, the anion is defined as the negatively charged ion, which is the chloride ion (Cl-). The NaCl structure features a face-centered cubic arrangement where the anions and cations alternate positions. To visualize this, a 3D figure of the NaCl lattice can be helpful, illustrating the arrangement of ions and their interactions. This understanding is crucial for accurately determining the ionic radius based on the unit cell dimensions and the assumption of direct contact between anions.

Q.The unit cube length of LiCl (NaCl structure) is 5.14 amstrong . Assuming anion-anion contact, calculate the ionic radius for chloride ion.

How to assume anion-anion contact ? Can anyone help with a 3D figure?

The NaCl structure is very easily found via an Internet search. Do you know which atom is the anion (i.e., how an anion is defined)?

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...
