Although it describes the trends, there isn't any attempt to explain them on this page - for reasons discussed later. Alkali metals belong to the s-block elements occupying the leftmost side of the periodic table.Alkali metals readily lose electrons, making them count among the most reactive elements on earth. Simple :-In the case of S block element we will see the difference in sizeof cation and anion i.e. There are solubility rules to follow when prdicting the solubility of a salt.see below. As a rule of thumb, if it fits any of the following criteria, it is soluble: * Acronym: NAACP #1 are all soluble no matter what.

The correct order of solubility of alkali metal fluorides in water is. Alkali metal salts are diamagnetic. METALLIC PROPERTIES: They are silvery white metals, soft in nature but harder than alkali metals due to stronger metallic bonding. The alkali metals have low melting points, ranging from a high of 179 °C (354 °F) for lithium to a low of 28.5 °C (83.3 °F) for cesium. This discussion on What is the solubility order of fluorides for alkaline earth metals? The elements are Lithium, Rubidium, sodium, Potassium and cesium. is done on EduRev Study Group by NEET Students. The correct order of solubility of the sulphates of alkaline earth metals in water is. This page looks at the solubility in water of the hydroxides, sulphates and carbonates of the Group 2 elements - beryllium, magnesium, calcium, strontium and barium. The salt containing one or more atoms of oxygen such as oxides ,hydroxides ,carbonate ,bicarbonate ,nitrite ,nitrate ,sulphates ,oxalates and phosphates are called oxo salts. Solution: The alkali metals are strong reducing agents, lithium the most and sodium the least powerful. Thus, the order for ionic mobility of ions is. Doubtnut is better on App. Doubtnut is better on App. However, these hydroxides are less basic than the corresponding alkali metal hydroxides because of higher ionization energies, smaller ionic sizes and greater lattice energies. Question from JEEMAIN-2016,jeemain,2016,chemistry,set b,09042016 Correct option (b) Rb + > K + > Na + > Li + Explanation: Hydration enthalpies of alkali metal ions decreases with the increase in ionic radii as we move down the group. The correct order of solubility of the sulphates of alkaline earth metals in water is 1:23 200+ LIKES. Explain the trends in the solubility of carbonates , sulphates and hydroxides of alkaline earth metals. The correct order of the solubility of alkaline- earth metal sulphates in water is : 1. most sulfates are soluble except BaSO4, Hg2SO4,PbSO4 and CaSO4 sulfate. Solubility is the maximum amount a substance will dissolve in a given solvent. Solubility: The solubility of the sulphates in water decreases down the groups i.e. Rb + > K + > Na + > Li + Stability of carbonates increases down group I (alkali) and group II (alkaline earth) metals. The sulphates of alkaline earth metal are prepared by the action of sulphuric acid on metals, metal oxides ,hydroxides and carbonates. The correct order of the mobility of the alkali metal ions in aqueous solutions Rb+ > K+ > Na+ > Li+ due to following order of hydration energy of these ions Li+ > Na+ > K+ > Rb+ and due to hydration of ion, mobility decreases. The carbonate ion has a big ionic radius so it is easily polarized by a small, highly charged cation. Carbonates of metal: Thermal stabilityThe carbonates of alkali metals except lithium carbonate are stable to heat. Order of solubility of sulphate of Alkaline earth metals BeSO 4 > MgSO 4 > CaSO 4 > SrSO 4 > BaSO 4 The greater hydration enthalpies of Be 2+ and Mg 2+ ions dominate over their lattice enthalpies and therefore their sulphates are highly soluble. Compare the solubility and thermal stability of the following compounds of the alkali metals with those of the alkaline earth metals. The alkali metals have the silver-like lustre, high ductility, and excellent conductivity of electricity and heat generally associated with metals. The smaller size and the charge density increases the hydration energy of the beryllium sulphate leading to more solubility. The right order of the solubility of sulphates of alkaline earth metals is : (A) Be > Ca > Mg > Ba > Sr (B) Mg > Be > Ba > Ca > Sr (C) asked Oct 13, 2019 in S - block elements - alkali and alkaline earth metals by Rk Roy ( 63.6k points) The carbonates of group-2 metals and that of lithium decompose on heating, forming an oxide and carbon dioxide . Lithium is the lightest metallic element. The correct order of the solubility of alkaline- earth metal sulphates in water is : The correct order is . The sulphates of alkaline earth metals are all white solids. Trump suggests he may not sign $900B stimulus bill. Open App Continue with Mobile Browser. The correct order of solubility of alkali metal fluorides in water is . solubility is directly proportional to difference in size As here,alkali metal fluoride so LiF,NaF,KF,RbF,CsF. are solved by group of students and teacher of NEET, which is also the largest student community of NEET. The solubility order of metal hydroxides is as follows: Group IA elements are called as alkali metals. Thatâs the reason all these elements are placed in the IA group of âthe periodic tableâ. Contrary to alkali metal sulphates, beryllium sulphate is water-soluble. The correct order of the solubility of alkaline-earth metal sulphates in water is: - 7941361 Be > Mg > Ca > Sr > Ba. 5.4k SHARES. MF 2 > MCl 2 > MBr 2 > MI 2. 5.5k VIEWS. Hence, the order of their solubility is : L i O H < N a O H < K O H < R b O H < C s O H. Answer verified by Toppr .
