(b). REASONS: there is a little change in the lattice enthalaphy BUT as the cation gets larger the hydration enthalaphy gets much smaller a large cation has a lower charge density and so is less attracted to water. An aqueous solution of calcium hydroxide is called lime … As you go upward in the alkaline earth list the molecules are larger and have larger positive charges. Why did clay walker and Lori lampson get divorced? The hydration enthalpy decreases due to the continuous increase in the size of cation down the group. Join now. Therefore, the smaller the ion, the higher the hydration enthalpy. According to Table 13.2, alkaline earth metal nitrates and chlorides are soluble in water. Join now. rep urges Belichick to decline Trump's medal offer, Twitter shares tumble after site permanently bans Trump, SCOTUS rejects fast track for Trump election cases, Trump remains defiant amid calls to resign, Marriott shuns lawmakers who balked at certification, Trump faces a new challenge in his final days. The material on this site can not be reproduced, distributed, transmitted, cached or otherwise used, except with prior written permission of Multiply. So, enthalpy change of solution becomes more endothermic. 1. Therefore, the lattice enthalpy decreases much slower when progressing down the group compared to the case of Group 2 OH⁻ compounds. 1 Answer to why solubility of hydroxides of alkali earth metals increases down the group while the solubility of sulphates of alkali metals decreases down the group? No. Log in. Problems with the usual explanations. Firstly, we must consider the thermodynamics involved. A shorter bond would require more heat energy to be broken. Since the hydration enthalpies decrease down the group solubility will decrease as found for alkaline earth metal carbonates and sulphates. 1. Generally, Group 2 elements that form compounds with single charged negative ions (e.g. 1 Questions & Answers Place. All Rights Reserved. Republican forces vote on 25th Amendment resolution, Acting Homeland Security chief Chad Wolf to resign, Hailie Deegan apologizes for use of slur in broadcast. I wish to understand the reason … Let's deal with OH⁻ first. However, they dissolve in water containing CO 2 yielding bicarbonates, and this solubility decreases on going down in a group with the increase in stability of carbonates of metals, and decrease in hydration energy of the cations. The same thing applies to the cation while progressing down the group. 4. Solubility of sulphates and carbonates of alkaline earth metals decreases as the atomic number of the metal increases down the group because the size of the cation increases down the group. Therefore, the shorter the bond, the higher the lattice enthalpy. Copyright © 2021 Multiply Media, LLC. What does contingent mean in real estate? The lattice dissociation enthalpy and hydration enthalpy both decrease as you go down the group. The assumption is made that the more endothermic (or less exothermic) the enthalpy of solution is, the less soluble the compound. Now let's look at SO₄ ²⁻. Why does the solubility of group 2 sulphates decrease down the group - 3653972 As you go down the Group 2 elements, d orbitals become available, even though they are empty in the ground state. Chemistry. This simple trend is true provided hydrated beryllium sulfate is considered, but not anhydrous beryllium sulfate. All Group II hydroxides when not soluble appear as white precipitates. Why does the solubility of sulphates decrease down group 2? All Group II hydroxides when not soluble appear as white precipitates. Please explain the text in bold. However, they dissolve in water containing CO 2 yielding bicarbonates, and this solubility decreases on going down in a group with the increase in stability of carbonates of metals, and decrease in hydration energy of the cations. (i) Why does the solubility of alkaline earth metal hydroxides in water down the group? Problems with the data. The ability of alkaline earth metal cations to hydrate themselves decreases down the group due to decrease in charge density. Solubility of the sulfates. REASONS: there is a little change in the lattice enthalaphy BUT as the cation gets larger the hydration enthalaphy gets much smaller a large cation has a lower charge density and so is less attracted to water. Mg 2+ (aq) reacts with NaOH to form a white precipitate because Mg(OH) 2 is insoluble (only sparingly soluble). The size of anions being much larger compared to cations, the lattice enthalpy will remain almost constant within a particular group. Going down the group, the first ionisation energy decreases. The solubility of sulphates of alkaline earth metals in water decreases down the group i.e going from BeSO 4 to BaSO 4. Chemistry. Can you explain what the changes in … However, due to the square factor, the lattice enthalpy decreases faster than the hydration enthalpy. The correct option is A. While progressing down Group 2, the size of the cation increases since the number of shells increases to accommodate to the extra electrons. For any compound if H. E > L. E then the compound is soluble in water. As we go down the group the size of cation increases due to which both H. E and L. E decreases but due to large size of anion (Carbonate and Sulfate) the H. E decreases more rapidly than L. E. Hence carbonates and sulfates solubility decreases down the group. BUT FOR THE MOMENT, As my question said "Why the water solubility of Sulfates decrease when moving down the Group IIA?"
