WebThe concept of lattice energy was originally applied to the formation of compounds with structures like rocksalt and sphalerite where the ions occupy high-symmetry crystal lattice sites. In the case of NaCl, lattice energy is the energy change of the reaction Na + (g) + Cl − (g) → NaCl (s) which amounts to −786 kJ/mol.

WebWhen, however, an ionic compound such as sodium chloride (NaCl) dissolves in water, the sodium chloride lattice dissociates into separate ions which are solvated (wrapped) with a coating of water molecules. Nonetheless, NaCl is said to dissolve in water, because evaporation of the solvent returns crystalline NaCl. 1 comment ( 5 votes) Upvote WebSodium oxide must have the N a O 2 formula unit because oxygen ions have the 2 − charge state and sodium ions have the 1 + charge state. The ionic lattice can only have zero electric charge if there are two sodium ions for every oxygen ion. This implies that option E is wrong, and option A must be correct.

WebSodium oxide is produced by the reaction of sodium with sodium hydroxide, sodium peroxide, or sodium nitrite: [5] 2 NaOH + 2 Na → 2 Na 2 O + H 2 To the extent that NaOH is contaminated with water, correspondingly greater amounts of sodium are employed. Excess sodium is distilled from the crude product.
