The balanced equation will be calculated along with the solubility states, complete ionic equation, net ionic equation, spectator ions and precipitates. 元素中的第一个字符使用大写字母,第二个字符使用小写字母。例子:Fe, Au, Co, Br, C, O, N, F。 替换不可改变的组以避免歧义。例如,C6H...
It could be attributed to the solubility of Ba(NO 3 ) 2 in water being less than that of Sr(NO 3 ) 2 .吴立军李超荣陈万春梁敬魁中国物理快报:英文版WU Li-Jun,LI Chao-Rong,CHEN Wan-Chun,LIANG Jing-Kui. Role of Ba2+ Ion in the Crystal Growth of Sr(NO3)2[J]. 2000.Wu, L.J.,...
The solubility isotherms of the M(NO3)2 - H2O - CH3OH (M = Sr, Ba) systems at 25 °C have been studied. Crystallization fields of the equilibrium existence of the salts Sr(NO3)2 .4 H2O, Sr(NO3)2 and Ba(NO3)2 have been found. The structures of the saturated solutions on the ba...
Study of the Ternary Systems M(II)(NO3)2–LiNO3–H2O (M(II)5Mg, Ca, Sr, Ba) at 25°C The isothermal solubility diagrams of four aqueous systems containing lithium nitrate and nitrates of group IIA metals – magnesium, calcium, strontium, an......
2. Experimental 2.1. Materials First, Sr0.9−x−y−zCa0.1In2O4:(xEu3+, yTm3+, zTb3+ mol%) powders were synthesized by the ultrasonic spray pyrolysis method (USP) [24], [28]. Strontium nitrate [Sr(NO3)2] (Alfa Aesar, 99% purity), calcium nitrate tetrahydrate [Ca(NO3)2∙4 ...
A possible driving force for the crystallization is originated from the difference in the solubility of the two solid phases at a given temperature. The formation of γ phase on the α phase dissolving below 0°C was also observed, instead of the peritectic reaction. In this process, the α...

Given the high solubility of Zn in aqueous solution, it may have accumulated in the tissue as aqueous Zn. Zn and Cu are essential trace elements for humans; therefore, it is difficult to distinguish the accu- mulated elements of eroded dental alloy components from pre-existing endogenous trace...
