Since the maximum contaminant level (MCL) for THMs in drinking water is 0.08 mg/L (or 0.05 mg/L for CHCl 3) [ 27 ], analysis of the water samples for chloroform based on the designed device is recommended. WebSolubility and miscibility describe similar phenomena, but they are not the same. Solubility exists on a spectrum. Substances may combine together poorly or very well, and it's possible to describe solutions as "partially soluble" or "mostly soluble." Miscibility, however, is an absolute property that is not expressed in degrees.
