They are all gases at standard pressure. The stronger covalent bonds of water (which is also held together generally by hydrogen bonds between water molecules) win out, and NaCl is pulled apart, with the Na+ and Cl_ ions setting loosely in place between the intact H2O molecules. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739.

The mass of dry lead(II) bromide is 0.045 g. The balanced chemical equation is below. When KBr dissolves in water, aqueous K* and Br ions form. Transcribed image text: Some KBr is dissolved in water. Images were acquired with an Olympus Keenview CCD camera (formerly Soft Imaging). In neither case is a true bond created, but the attractions set up a "tug-of-war" in which the ionic bonds of NaCl and the covalent bonds of H2O are both strained. Based only on intermolecular forces, which of the following would be the most soluble in, A:Solubility depends on the interaction of solute and solvent. https://doi.org/10.3390/nano13020370, Menezes T, Bouguerra S, Andreani T, Pereira R, Pereira C.
