就是这句话的解释:ionic compounds are often soluble in water because water is a polar molecule and is attracted to the ions.要的是解释不是翻译(不是很理解“water is a polar molecule and is attracted to the ions” 相关知识点: 试题来源: 解析 由离子构成的分子,遇水会进行离子的游离,与水中的H...
However, not all ionic compounds are soluble in water, as some are simply too large or have too strong of ionic bonding to dissolve. Ionic compounds are also known for their ability to conduct electricity. When ions are present in a substance, they carry an electrical charge that can be ...
If, on the contrary, intramolecular forces are stronger, it is not soluble or sparely soluble. The solubility of ionic compounds The basic guideline is: Ionic compounds are soluble. The more ionic, the more soluble, since the interaction between ions and solvent (usually water) is strong enou...
Is the compound Be(OH)2 soluble or insoluble in water? Explain. Is the compound Ca3(PO4)2 soluble or insoluble in water? Explain. Is the compound (NH4)2CO3 soluble or insoluble in water? Explain. Is the compound Mn3(PO4)2 soluble or insoluble in water? Explain. ...
in water depends on the strength of the bonds holding the compound together compared to the strength exerted on the individual ions by the water molecules. Highly soluble compounds, such as NaCl, break apart completely, while compounds with low solubilities, such as lead sulfate (PbSO4) do so...

soluble in water. The quantity of residual Sr(OH)2·8H2O should be very small if there is any. In addition, STEM and EDX results indicate the presence of an amorphous material in the Y-rich area B (Supplementary Fig.3b, c), which is likely to be Y(OH)3. This amorphous material ...
It was shown that EDXRF application using vacuum medium led to mass loss of water soluble ionic compounds and other volatile constituents of PM10. The use of a He and air medium considerably reduced the PM mass losses. It is demonstrated that the mass loss of PM and ionic compounds mainly ...
