Sulphates: - The sulphates of both alkali and alkaline earth metals are thermally stable. c) is an example of two rules contradicting each other. (c)Sulphate-thermal stability is good for both alkali and alkaline earth metals. The alkali metals atoms have the largest atomic radii in their respective periods. This is because some magnesium hydroxide has dissolved. NCERT DC Pandey Sunil Batra HC Verma Pradeep Errorless. Which of the following is most soluble in water? A solution of K O H in water is called: View solution. 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 . The lattice energy remains constant because sulphate ion is so large, so that small change in cationic sizes do not make any difference. From Li to Cs, due to larger ion size, hydration enthalpy decreases. Alkali metal sulphates are more soluble in water than alkaline earth metals. Let us discuss the characteristics of the compounds of the alkali earth metals. Legal. Given that the ionic product of $Ni(OH)_2$ is $2 \times 10^{-15}$. Sulphates. In other sulphates, increasing lattice energy and the decreasing hydration energy (due to increasing size) decreases their solubility form BeSO 4 to BaSO4. JIPMER 2014: The correct order of solubility of the sulphates of alkaline earth metals in water is Be > Mg > Ca > Sr > Ba. The correct order of solubility of the sulphates of alkaline earth metals in water is 1:23 200+ LIKES. In fact, 1 liter of water dissolves about 2 mg of barium sulfate at room temperature. The Nuffield Data Book quotes anyhydrous beryllium sulfate, BeSO4, as insoluble, whereas the hydrated form, BeSO4.4H2O is soluble, with a solubility of about 39 g of BeSO4 per 100 g of water at room temperature. The following examples illustrate this trend: This simple trend is true provided hydrated beryllium sulfate is considered, but not anhydrous beryllium sulfate. Log in. Which among the following elements of group-2 exhibits anomalous properties ? Notice that a solution, and not a precipitate, is formed, implying that magnesium sulfate is soluble. The solubility of carbonates increases down the group in alkali metals (except ) . Of the following, which species is primarily obtained in a solution containing $KHF_2$ ? This indicates that there are more hydroxide ions in solution than there were in the original water. … Each of these elements contains two electrons in their outermost shell. As far as the solubility of sulphates of alkaline earth metal in water is concerned BeSO 4 and MgSO 4 are highly soluble , CaSO 4 is sparingly soluble, but the sulphates of Sr, Ba and Ra are virtually insoluble.

The bicarbonate of alkali metal which does not exist in solid state is: All the Group 2 carbonates are very sparingly soluble. The alkali metals are so called because reaction with water forms alkalies (i.e., strong bases capable of neutralizing acids). Secondary School. Solubility figures for magnesium sulfate and calcium sulfate also vary depending on whether the salt is hydrated or not, but the variations are less dramatic. But my textbook (Concise Inorganic Chemistry by JD LEE) says that the "Solubility of carbonates and fluorides of Alkali metals increase rapidly on descending the group. Two common examples illustrate this trend: The carbonates become less soluble down the group. If we consider the periodic table, the elements that would fall in the group 2 of the table are usually known as alkali earth metals. But carbonates of alkaline earth metals are insoluble in water. The high solubility of BeSO4 and MgSO4 is due to the high hydration enthalpy because of smaller size of Be2+ and Mg2+ ions. The solubilities of the hydroxides in water follow the order: Be(OH)2 < Mg(OH)2 < Ca(OH)2 < Sr(OH)2 < Ba(OH)2. How do I arrange the following alkaline-earth-metal sulfates in order of increasing solubility in water?
