Question

The concentration term 'Parts per million' (ppm) is primarily used for trace quantities. Depending on the physical states of the solute and solvent, ppm can be correctly expressed in which of the following formulations?

Answer: A,B,C,D

💡 Solution & Explanation

PPM represents one part in a million parts. Depending on the system, it can be defined contextually as mass of solute per $10^6$ units of solution mass ($w/w$), volume of solute per $10^6$ units of solution volume ($v/v$), mass per $10^6$ units of volume ($w/v$), or even as a mole ratio.
