State Henry’s law for solubility of a gas in a liquid. Explain the significance of Henry’s law constant (KH). At the same temperature, hydrogen is more soluble in water than helium. Which of them will have a higher value of KH and Why?

BySolutionlogy

Henry’s Law states that the solubility of a gas in a liquid is directly proportional to the partial pressure of that gas on the surface of the liquid, provided the temperature remains constant. Mathematically, it can be expressed as: C = KH​×P Where: Significance of Henry’s Law constant (KH​): The value of KH​ provides a…

What is meant by stock solution (or) standard solution? What is meant by working standard?

BySolutionlogy

In the context of calibration and quality control in analytical chemistry, a stock solution might be a primary standard (a compound of known purity). In contrast, a working standard would be a secondary standard (a solution prepared from the primary standard). The primary standard is used to prepare the secondary standard, and the secondary standard…
