Create and find flashcards in record time. A pH buffer system, which is usually a weak acid or base and its salt, is a common excipient used in liquid preparations to maintain the pH in a range that minimizes the drug degradation rate. The external factors are ambient temperature, collector voltage, circuit resistances, and the thermal coupling between the transistor and temperature . High temperature - Higher temperatures increase kinetic energy, which causes molecules to vibrate rapidly and forcefully. The primary environmental factors that can reduce stability include exposure to adverse temperatures, light, humidity, oxygen, and carbon dioxide. This factor requires that the center of the AO be as close as possible to the nucleus. Everything you need for your studies in one place. 1. Several factors affect the stability of the complexes: Nature of central metal ion Charge on metal cation When the metal cations and the metals are present in their higher oxidation state then they form complexes which are stable as compared to when they are present in their lower oxidation state. This value of Kstab is very high. For syrups, elixir or solution dosage forms in which there is nothing suspended, particle size and physical characteristics of raw materials are not that important. or potency of a product as these factors may .
