稀溶液依数性是大学无机化学和物理化学中较重要的内容之一。教学中,常配有一定的习题和教学实验。在科研和实际应用中,依数性公式也常被用来测定某些物理量,例如,测定物质分子量等。不管是在教学过程中,或者是在实际应用中,最常用的依数性公式是凝固点降低和沸点升高公式,其主要形式是其一级近似式△T=K·m。此式的近似性主要来自推导过程中的两个假设,即TT0=T_0~2和?in(1-X_B)=X_(Bo)
Dilute solution by the number of the University of inorganic chemistry and physical chemistry is one of the more important content. Teaching, often with some exercises and teaching experiments. In scientific research and practical applications, according to the formula is often used to determine the number of physical quantities, for example, determination of molecular weight and so on. Whether it is in the teaching process, or in practical applications, the most commonly used formula is based on the number of freezing point lower boiling point and boiling formula, the main form is its first approximation △ T = K · m. The approximation of this formula mainly comes from the two assumptions in the derivation process: TT0 = T_0 ~ 2 and ~ in (1-X_B) = X_ (Bo)
