AI Thread Summary
MAL, or Maximum Allowable Limit, refers to the permissible concentration of cadmium in drinking water, which is crucial due to the metal's harmful effects on human health. The US Environmental Protection Agency (EPA) has established a limit of 0.005 mg/L for cadmium, indicating that even this minuscule amount is undetectable to the naked eye. Additionally, the World Health Organization (WHO) recommends an even lower limit of 0.003 mg/L. Understanding these limits is essential for ensuring safe drinking water and protecting public health from cadmium exposure.

TL;DR Summary
Mal of Cadmium in soft water
What does ‘MAL (is it Maltol) of cadmium’ in soft water mean?
 
Chemistry news on Phys.org
MAL = maximum allowable limit - Cadmium is not good for humans to ingest or drink, so acceptable levels of cadmium in drinking water, for example, have limits. VERY small ones.
US EPA has set a limit of .005mg/L - You could not see a .005mg speck of Cadmium with the naked eye.

Many thanks. Who guidance .003mg/L. No problem. Thanks for simplifying that riddle.
 

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 'Why does having 8 valence electrons make an element inert?'

I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!

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...
