“十字交叉法”不但对任何物质的稀释计算有着广泛地应用,而且对结晶水合物配制溶液的计算也有它的独到之处。众所周知,为了将某种浓度的溶液稀释到一定的浓度或者将两种不同浓度的同类溶液相混和,以便配制一种新浓度的溶液时,总是从新溶液中所含的溶质总量与稀释或混和时各组分中所含溶质总量相等这一点出发来建立特定的数量关系,而这种关系恰恰可以由“十字交叉法”反映出来。
The “cross-crossing method” is widely used not only for the dilution calculation of any substance, but also for the calculation of a crystalline hydrate preparation solution. It is well known that in order to dilute a certain concentration of solution to a certain concentration or to mix two different concentrations of the same type of solution so that a new concentration of solution is prepared, the total amount of solute contained in the new solution is always diluted with The specific amount of solute contained in each component in the mixture is equal to establish the specific quantitative relationship, and this relationship can be precisely reflected by the “crossing method”.
