Second ionization energy for sodium

AI Thread Summary
The first ionization energy of sodium is significantly lower than the second ionization energy due to the electronic configuration of sodium. When sodium loses its first electron, it achieves a stable noble gas configuration, resembling neon. This stability makes the removal of the first electron easier. In contrast, the second ionization involves removing an electron from a positively charged ion (Na+), which requires more energy due to the increased effective nuclear charge acting on the remaining electrons. Thus, the energy required to remove the second electron is much higher than that for the first.

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...
