新西兰环球理工学院论文代写:导电性元素

在导电性方面,有两个可以讨论的元素。一个是导电性,第二个是导热性。氯化钙在熔融状态下被认为是非常好的导体或电,但是就导热性而言是非常不良的导热体(氯化钙的性质,2015)。类似地,就硫酸镁和氯化镁而言,可以看出,颗粒形式不导电,它必须稀释成液体形式用于传导电。这些溶液的导电强度将基于浓度而变化。知道浓度实际上将产生更多的盐的实际应用。

因此,可以确定包括MgSO 4,MgCl 2和CaCl 2的水溶液的电导率作为它们的浓度的函数。随着温度固定在例如20℃,则电导率可以表示为值κ。这是电导率的电导率,是电阻率的倒数(Weast,1989; Wolf 1966)。摩尔电导率Λ通过方程Λ=κ/ c给出。这里c是电解质的浓度。这样,氯化钙CaCl2在0.5%质量浓度下的导电率为8.1,1%为15.7,2%时为29.4等。对于氯化镁,0.5%时的导电率为8.6,1%时的导电率为16.6,2%时的导电率为31.2等。对于硫酸镁MgSo4,它分别为4.1%,7.6%和13.3%,分别为0.5%,1%和2%(科罗拉多州,2015)。因此可以看出,在0.5%氯化镁得到比氯化钙或硫酸镁更好的导电性。这种更好的电导率趋势也随着溶液浓缩物而改善。盐的浓缩性质因此基于它们的浓度和基于单独的盐影响电导率。

In terms of conductivity, there are two elements that can be discussed. One is that of electrical conductivity and the second is thermal conductivity. Calcium chloride in molten state is seen to be a very good conductor or electricity, however in terms of thermal conductivity is a very bad conductor of heat (Properties of Calcium Chloride, 2015). Similarly in terms of Magnesium Sulfate and Magnesium chloride it is seen that the particle form does not conduct electricity, it has to be diluted to liquid form for the conduction of electricity. The conductivity strength of these solutions will vary based on the concentrations. Knowing the concentration will actually generate more practical applications for the salts.

The electrical conductivity of aqueous solutions including MgSO4 , MgCl2 and CaCl2 can hence be determined as a function of their concentration. With temperature being fixed say at 20 °C, then the conductivity can be presented as value κ. This is the specific conductance and is resistivity’s reciprocal (Weast, 1989; Wolf 1966). The molar conductivity Λ is presented by means of the equation Λ = κ/c. Here c is the concentration of the electrolyte. With this, the electrical conductivity for Calcium Chloride CaCl2 at o.5 percent mass concentration is 8.1, at 1 percent it is 15.7, at 2 percent it is 29.4 and so on. For Magnesium chloride the conductivity that is given at 0.5 percent is 8.6, at 1 percent is 16.6, at 2 percent it is 31.2 and so on. For Magnesium Sulfate MgSo4 it is 4.1, 7.6 and 13.3 for 0.5 percent, 1 percent and 2 percent respectively (Colorado State, 2015). It is seen hence that at 0.5 percent Magnesium chloride gives better conductivity than that of Calcium Chloride or Magnesium Sulfate. This better conductivity trend also improves with the solution concentrate.  The concentrative properties of salts hence affect the electrical conductivity based on their concentrations and based on the individual salt.
