Solubility of a salt in water depends on Lattice energy versus hydration energy Lattice energy (amount of energy required to break one mole of a solid salt into its ions). Greater the lattice energy, more will be the energy required to break the lattice. Hydration energy (amount of energy ..

(called hydration energy) is released in the third step. This compensates the higher energy needed to remove electron in second step. The net effect is that it has greater tendency to lose electrons in solution than other alkali metals and the reaction: Therefore, lithium is the..

H h y d r a t i o n = - 2760 kJ mol - 1 Net Energy change = - 874 kJ mol - 1 Thus, it is clear that during the formation of MgCl2 in water, more energy is released and accordingly it is more readily formed. 9. What are the factors that govern the solubility of a salt in wate..

It is the amount of energy released when one mole of the ions undergo complete hydration in aqueous solution..

Consider a zinc rod being dipped in ZnSO 4 solution. The zinc atoms on the surface of the metal with in the solution have tendency to release Zn + 2 into solution retaining the electrons on the surface of the metal. This process is called dissolution..

Question 1 - Question: Define the terms: Acid, alkali and salt. Answer: An acid is a compound, which releases hydronium ions (H 3 O + ) as the only positive ions in solution. An alkali is a compound, which releases hydroxyl ions (OH - ) as the only negative ions in ..

Take small pieces of ripe banana, potato and lemon. Crush them separately, strain their juice and put 10 drops of their juices into different test tubes. Add a few drops of Benedict's solution to the juices and heat them. You will notice that the test tube containing the ripe banana juic..

Hydrogen gas has explosive flammability and so is difficult to handle. This causes problem to its storage and transportation. A solution for this is the use of Fe-Ti alloy, which absorbs hydrogen and results in the formation of fine silvery powder. Heating the powder safely releases..

Find the optimal solution in the above problem of decorative item dealer whose objective function is Z = 50x + 18y. In the graph, the corners of the feasible region are O (0, 0), A (0, 80), B(20, 60), C(50, 0) At (0, 0) Z = 0 At (0, 80) Z = 50 (0) + 18(80) = Rs. 1440 At (20, 6..

Question: What is the action of Na 2 CO 3 solution on litmus and why? Answer: In solution Na 2 CO 3 salt undergoes hydrolysis and releases OH - ions from the stronger alkali NaOH. Consequently, the resulting solution is basic and turns red litmu..
