Question:
A solution was made by adding 0.291 grams of copper (II) thiocyanate to a 500 mL volumetric flask and diluting to the mark. Determine the concentrations in the solution:
A) ppm copper (II) thiocyanate AND ppm copper (II) ion
B) ppm thicyanate ion AND ppm sulfur AND ppm nitrogen
Parts per Million:
Parts per million is a pseudo-unit which is used by scientists to describe quantities of small values. It is usually abbreviated as ppm which can also be expressed as milligrams per liter {eq}\frac{mg}{L}{/eq} or microgram per milliliter {eq}\frac{\mu}{mL}{/eq}. Moreover, this concentration can be applied to quantify contaminants per unit volume of water or soil.
