AS REPORTEDno primary record reached; this is what the reporting says
Standard chemical solubility rules report that sodium salts are generally soluble in water, refuting the assertion that certain sodium salts are completely insoluble.
A wide variety of units of concentration can be used for this purpose. When describing how much of a given solute dissolves in water, the most common, "universal" solvent, the semi-quantitative terms: soluble, slightly soluble, and insoluble, can be used. These terms are applied quite loosely, and there tends to be substantial variation in the ranges of these categories and other descriptive terms. A more detailed treatment will be provided in a later workshop, Solutions. A table and a set of a few generalized rules follow that summarize the solubility characteristics of a number of compounds. Simple Solubility Rules for Ionic Salts in Water
- Most nitrate (NO3–) salts are soluble. - Most sodium, potassium, and ammonium (Na+, K+, NH4+) salts are soluble. - Most chloride (Cl–) salts are soluble. Notable exceptions are AgCl, PbCl2, and Hg2Cl2. - Most sulfate (SO42–) salts are soluble. Combinations with sulfate ion which form insoluble compounds are: SrSO4, BaSO4, Hg2SO4, Ag2SO4, and PbSO4. - Most hydroxide (OH–) salts are only slightly soluble. The important soluble hydroxides are NaOH, KOH, and Ca(OH)2.
