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. 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

WebThe simultaneous substitution of sodium and cerium ions in place of barium ions (N a B a + a n d C e B a 3 + versus 2 · B a 2 +) eliminates the charge compensation problem. Therefore, sodium ions help barium ions enter the crystal lattice and increase the number of barium ions in the lattice.
