So, for alkali metal chlorides, anion that is chloride here is fixed. Data , 1979 , 24 (4), pp 338–340 For example, sodium carbonate is soluble because all sodium compounds are soluble, even though most carbonates are insoluble. These rules are general and qualitative in nature. So, greater will be the difference in size of combining atoms greater will be the solubility. (Some sources consider MgS, CaS and BaS to be slightly soluble.) Handbook of Solubility of the Academy of Sciences of the USSR [in Russian], Vol. As salt is a sulfate, the solubility differs depending on the type of salt and whether the salt is hydrated or not. Ammonium sulfide is soluble. As a result, there will be decrease in solubility. Solubility of water in molten alkali chlorides Abstract The solubility of water in molten mixtures of lithium chloride and potassium chloride containing 50.0, 53.0, 60.0, and 68.6 mole per cent lithium chloride was determined at 480 and 390oC in the pressure range zero to A Table for the Solubility of Salts in Water. … They are generally poorly soluble in organic solvents. NaOH + HCl ———> NaCl + H 2 O. OSTI.GOV Journal Article: Solubility of some alkali and alkaline earth chlorides in water at moderate temperatures Solubility is the maximum amount a substance will dissolve in a given solvent. Remember, solubility depends on the temperature of the water. "Ionic" metal halides (predominantly of the alkali and alkali earth metals) tend to have very high melting and boiling points. They freely dissolve in water, and some are deliquescent. Halides. Each rule has exceptions and the important ones are noted. Solubility of some alkali and alkaline earth chlorides in water at moderate temperatures M. A. Clynne , and R. W. Potter II J. Chem. 47, edited by Cohen-Adad, R. and Lorimer, J. The solubility of the most of alkali metal halides except those of fluorides decreases on descending the group since the decrease in hydration energy is more than the corresponding decrease in the lattice energy. 3) Formation of salts with acid: Alkali metal hydroxides being strongly basic react with all acids forming salts. Solubilities covered are lithium chloride, sodium chloride, potassium chloride, rubidium chloride, caesium chloride and ammonium chloride in water and heavy water. Compounds that don't dissolve around room temperature may become more soluble in warm water. Stack Exchange network consists of 175 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share … So, for alkali metal chlorides, anion that is chloride here is fixed. Therefore, the solubility data of these alkali metal salts in water vapor at high temperatures and pressures are very important as a fundamental knowledge to design the supercritical water decomposition processes. 2) The solubility of most of the alkali metal halides except those of fluoride decreases on descending the group since the decrease in hydration enthalpy is more than the corresponding decrease in the lattice enthalpy. So, greater will be the difference in size of combining atoms greater will be the solubility.
