Lithium-ion is the smallest in size and we know smaller the size of ion, the more hydrated it is. Why are alkali metals not found in nature ? Comment on each of the following observations: (a) The mobilities of the alkali metal ions in aqueous solution are Li+ < Na+ < K+ < Rb+ < Cs+ (b) Lithium is the only alkali metal to form a nitride directly. Electronic configuration of. (a) Na (b) K (c) Rb (d) Cs, Which one of the following alkali metals gives hydrated salts ? Halides. As we move down the group reactive nature increases. If you have a doubt or question that is not available here or in any of the chapters, contact us. These are the detailed explanation of NCERT textbook questions. Act as a reducing agent but not as powerful as alkali metals. [ M = Be, Mg, Ca, Sr, Ba] (b) Carbonates- Alkaline earth metal carbonates decompose on heating gives carbon dioxide and oxide. (iv) Solubility of carbonates and sul­phates decreases down the group. Start studying Solubility Rules. They produce the metal nitrite and oxygen, but no nitrogen dioxide: $2XNO_3 (s) \rightarrow 2XNO_2(s) + O_2 (g)$ Each of the nitrates from sodium to cesium decomposes in this way; the only difference is in the temperature required for the reaction to proceed. Mg helps in maintains normal blood circulation in our body. (b) alkali metals are prepared by electrolysis of their fused chlorides ? KnopmanMarks. All nitrates, acetates, hydrogen carbonates, and chlorates are… All Alkali metals and Ammonium compounds are soluble. Lithium-ion is the smallest in size and we know smaller the size of ion, the more hydrated it is. The carbonates and sulphates of alkaline earth metals are less soluble than corresponding alkali metals . (4) Chlorides, bromides, and iodides are soluble Alkali earth metals form solid carbonates. The solubility data at 1 bar or saturation pressure for sodium nitrate are reviewed. Lithium forms monoxide, sodium forms peroxide, the other metals form superoxides. (iii) sodium peroxide dissolves in water ? General electronic configuration of Group 1 elements is, 2. In s-block, there is a total of two groups (1&2). Alkali metal salts are soluble and nitrate salts are not. Down the group thermal stability of nitrates increases. All nitrates are soluble. (b) Because their oxides are themselves are a very strong reducing agent in nature. 2H2O. Question 10.25 What happens when (i) sodium metal is dropped in water ? Any substance that fails to reach 0.1 M is defined to be insoluble. Q9. Solubility in water is related to the ionic nature and size. Heating the nitrates. General electronic configuration of Group 2 elements is, NCERT Solutions for Class 11 Chemistry Chapter 10 The s-Block Elements - Exercise Questions. 3. That’s … Sodium reacts vigorously with oxygen and forming sodium peroxides. Data on some, such as cesium and rubidium fluoride, nitrate, carbonate, and sulfate, appear to be reported for the first time. Nitrates of other alkali metals on decomposition gives corresponding nitrite. 2LiNO3 → Li2O + 2NO2 + O2 2Ca (NO3)2→ 2CaO + 4NO2 + O2 Hence it is more soluble in methanol. Most nitrates tend to decompose on heating to give the metal oxide, brown fumes of nitrogen dioxide, and oxygen. All nitrates are soluble in water. Hence ion can easily polarise ions and making it unstable and because of that lattice energy of is not very high and so it is soluble in water. Solubility of sulphates: Sulphates formed by alkali metals are highly soluble and form alums very easily. : Some Li + are insoluble, with Li 3 PO 4 being the most common example. The IUPAC Solubility Data Series documents found on this site are web-versions of the volumes. Learn vocabulary, terms, and more with flashcards, games, and other study tools. How to prepare for KVPY 2021? Any substance that can form 0.1 M or more concentrated is soluble. They burn vigorously in oxygen forming oxides.
