The solubility v temperature phase diagrams for magnesium, calcium, strontium and barium oxide solutions, in lithium, sodium and potassium chloride melts and in the alkaline earth metal chloride melts, have been analysed. LiF is soluble in non-polar solvents like kerosene. The alkali metals are potent reductants whose chemistry is largely that of ionic compounds containing the M + ion. Data on some, such as cesium and rubidium fluoride, nitrate, carbonate, and sulfate, appear to be reported for the first time. The elements in Group 2 are called the alkaline earth metals. BeO and Be(OH)2 are amphoteric and react with acids and strong bases such as NaOH. 2 Citations. Ammonium (NH 4 +) compounds are soluble. 1. Maths.
