As with the alkali metals of Group 1 (Ia), the atoms of the alkaline-earth metals easily lose electrons to become positive ions (cations). Most of the alkali metal salts are soluble in water while many alkaline earth salts have very low solubilities. Smaller ions have higher charge density and can be solvated by more water molecules. Once the metals are removed from the solutions record your observations (any changes in color, size, texture) in data table 1. The Alkaline Earths as Metals OUTLINE 1.1.

Another way to prevent getting this page in the future is to use Privacy Pass. The nitrate salts tend to be soluble, but the carbonates and sulfates of the heavier alkaline earth metals are quite insoluble because of the higher lattice energy due to the doubly charged cation and anion. group 2 elements. When dissolved in water they form alkaline (basic) solutions. Most of their typical compounds are therefore ionic: salts in which the metal occurs as the cation M 2+, where M represents any Group 2 atom. sol: Na, K, NH4 insol: most. The concentration of chromate ion can be easily regulated through controlling the [H+] so that in the buffer system BaCrO 4 Alkaline earth metals get the name 'alkaline' because of the basic nature of the compounds they form when bonded with oxygen. I'm having a little trouble determining the solubility of Alkaline Earth Metals (NOT Alkali Metals). The alkaline earth metals form difluorides that are insoluble.
