The alkaline earth metals are six chemical elements in group 2 of the periodic table.They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). Periodic trends are observed in the solubility of alkaline earth metal compounds. Group 2, Alkaline Earth Metals. Group IIA (Alkaline earth metals) and groups IIB (Zn, Cd, Hg) Mg acts as a bridge element between IIA and IIB. The solubility of the alkaline earth metal hydroxides in water increases with increase in atomic number down the group. Only the lightest element (Be) does not react readily with N 2 to form the nitride (M 3 N 2 ), although finely divided Be will react at high temperatures. Like alkali metals, alkaline earth metals are also highly reactive and hence do not occur in the free state but are likely distributed in nature in the combined state as silicates, carbonates, sulphates and phosphates. Log in. Actually I have to tell you it ranges from “not very” to “almost completely insoluble”. http://wps.prenhall.com/wps/media/objects/3080/3154577/blb0405/blb04t02.gif, Researchers find nonnative species in oahu play greater role in seed dispersal networks, "Swiss Army knife" catalyst can make natural gas burn cleaner, Levels of stress hormone in saliva of newborn deer fawns may predict mortality, Solubility of Metal Hydroxide in Solutions, Entropy changes for reactions: Understanding Periodic Trends, Theory or Reality - Acid/base trends on the periodic table. Carbonates of alkaline earth metals decompose easily upon heating. This question illustrates it well. Only the lightest element (Be) does not react readily with N 2 to form the nitride (M 3 N 2 ), although finely divided Be will react at high temperatures. Edexcel Chemistry. In part A, the reactions of magnesium, calcium, and aluminum with water and acids will be compared in order to determine the trend in metal activity within a group (Mg vs. Even ignoring entropy (to a first approximation we might assume that the entropy change is constant for all the metals), solubility depends on both lattice energy and hydration enthalpy so you can't just look at one trend. Solubility in water is related to the ionic nature and size. Please help me to understand the solubility trend of group 2 salt trend? Reactions in Water.

Why Solubility of Alkaline Earth Metals decreases down the Group? Colours of metal sulfides are important in identifying compounds in inorganic chemistry. It is measured in either, grams or moles per 100g of water. Magnesium carbonate, for example, has a solubility of about 0.02 g per 100 g of water at room temperature. Using your knowledge of periodic trends and the energetics of formation of solutions, explain why cations derived directly from alkali metals are usually soluble, but this is less the case for alkaline earth metals. Solubility is the maximum amount a substance will dissolve in a given solvent. All the alkaline earth metals except beryllium also react with water to form strongly alkaline hydroxides which should be handled with great care. Also, discuss how these would be affected in the case of solvation with sulfide ions. Some examples may help you to remember the trend: Magnesium hydroxide appears to be insoluble in water. The size of the alkaline earth cations increases with increasing atomic number, and the calcium ion is bigger than the magnesium ion. When added to water, the first alkaline earth metal (Beryllium) is totally unreacative, and doesn't even react with steam.Then as you move down the group, the reactions become increasingly vigourous.. As an example, the following reaction takes place between magnesium and water, an alkali earth metal hydroxide and hydrogen gas is produced. Answer Save. Log in.
