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. Doubtnut is better on App. Start studying Solubility of Group 2 Hydroxides and Sulphates. All Group II hydroxides when not soluble appear as white precipitates. Arrange sulphates of group `2` in decreasing order of solubility of water. 1. Paiye sabhi sawalon ka Video solution sirf photo khinch kar. Log in. Again, the hydration enthalpy decreases the same way as it does in the case of Group 2 cations bonded to OH⁻ ions. AIIMS 1999: The solubility in water of sulphates down the Be group is Be > Mg > Ca > Sr > Ba. Arrange these in the order of decreasing solubility, and give reasons for each… Solubility of the sulphates. Can you explain what the changes in enthalpy are in each case? Solubility of group 2 sulphates and hydroxides Watch. On moving down the group, their solubility decreases. Books. Group 1 nitrate do not decompose in the same way as group 2 with the exception of Lithium nitrate. Since the hydration enthalpy decreases faster than the lattice enthalpy in the case of Group 2 sulphates, the solubility of Group 2 sulphates decreases while progressing down the group. This is due to asked Jan 1, 2019 in S-Block Elements by kajalk ( 77.6k points) Secondary School. I've been reading about it and it seems to have something to do with the reverse lattice enthalpy and the enthalpy of hydration. For Group 2, magnesium sulphate is soluble while strontium and barium sulphates are insoluble. The sulfate anion consists of a central sulfur atom surrounded by four equivalent oxygen atoms in a tetrahedral arrangement. Barium hydroxide is soluble enough to be able to produce a solution with a concentration of around 0.1 mol dm-3 at room temperature. We however also need to consider lattice energy for the complete analysis. The solubilities of these salts further increase on moving down the group from top bottom!
