摘要
测定了晶态/非晶态多水硼镁石、章氏硼镁石和三方硼镁石水溶液在298 K等温蒸发过程中溶液在298.15 K的密度﹑粘度、电导率和pH。通过pH和硼酸盐化学计量平衡常数计算,获得了溶液化学物种分布,并推测了其相应反应机理。
Density, conductivity, viscosity, and pH of crystalline and amorphous inderite, hungchaoite and rnacallisterite solutions during isothermal evaporation have been measured at 298. 15 K. The species distri- butions were calculated by Newton iteration method from pH and stoichiometric equilibrium constant of some borate species, and the hydrolysis mechanism of aqueous magnesium borates was speculated further.
