Figure 2 gives the same plots, and additionally indicates the 21 0 obj This is a trend which holds for the whole Group, and applies whichever set of data you choose. <. I was just wondering the solubilites of nitrates, chlorides, hydroxides, sulphates and carbonates. 10. <>/ProcSet[/PDF/Text/ImageB]/XObject<>>>/Rotate 180/Type/Page>> The hydrolysis of iron(III) ions in aqueous solution forms a series of soluble hydroxide complexes with associated equilibrium constants. This trend can be explained by the decrease in the lattice energy of the hydroxide salt and by the increase in the coordination number of the metal ion as you go down the column. The hydroxides of the alkali metals, lithium, sodium, potassium, rubidium, and cesium, are the strongest bases and the most stable and most soluble of the hydroxides. Just a brief summary or generalisation. I was just wondering the solubilites of nitrates, chlorides, hydroxides, sulphates and carbonates. endobj The hydroxides include the familiar alkalies of the laboratory and industrial processes. <> 2018-11-05T19:04:42Z Hydroxide salts of Group I components are dissolvable. Sodium hydroxide, NaOH, also known as caustic soda or lye, is of great industrial importance. uuid:c00a67f3-aca9-11b2-0a00-d0a88417fd7f The aim of this text is to show how the solubility (S) of metal hydroxides, oxide-hydroxides, and oxides can be calculated as function of the equilibrium pH of the solutions, taking into account the formation of various cationic and anionic species of metal aqua ions; however excluding all foreign ligands.
