Magnesium chloride crystal structure and detailed solution

Magnesium chloride crystal structure and detailed solution

Answer:

From the magnesium chloride crystals 4.06 g 1.9 g anhydrous magnesium chloride, the mass of the crystal water in the magnesium chloride crystals was 4.06 g-1.9 g = 2.16 g 2.16 ÷ 18 = 0.12 mol The amount of MgCl2 was 0.02 mol. It was found that 0.12 ÷ 0.02 = 6 Magnesium chloride crystals in the crystal water is 6 times the amount of Mgcl2 so n = 6 Chemical formula for Mgcl2 · 6H2O
In recent years, magnesium chloride as snow melting agent more and more put into use, will be a lot of magnesium chloride into the environment. In order to better understand the pros and cons of the impact of magnesium chloride on the environment, it is possible to evaluate the effect of magnesium chloride on the growth capacity of soil and grain (maize and wheat) by using ecological simulation method. The experimental method is to put different concentrations of magnesium chloride 0.05%, 0.1%, 0.2%, 0.4% into the soil after the same area in the same natural environment, corn, wheat. To study the effects of magnesium chloride on soil factors: salinity and pH
