Click For 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
Mal of Cadmium in soft water

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.

Thread 'Molecular-level explanation of macroscopic phenomena: dissolving'

What I know and please correct me: a macroscopic probe of raw sugar you can buy from the store can be modeled to be an almost perfect cube of a size of 0.7 up to 1 mm. Let's assume it was really pure, nothing else but a conglomerate of H12C22O11 molecules stacked one over another in layers with van de Waals (?) "forces" keeping them together in a macroscopic state at a temperature of let's say 20 degrees Celsius. Then I use 100 such tiny pieces to throw them in 20 deg water. I stir the...
