Step 1

For (a) $\mathrm{BaBr}_2 \cdot 2 \mathrm{H}_2 \mathrm{O}$, the cation is $\mathrm{Ba}^{2+}$ (barium) and the anion is $\mathrm{Br}^-$ (bromide). For (b) $\mathrm{AlCl}_3 \cdot 6 \mathrm{H}_2 \mathrm{O}$, the cation is $\mathrm{Al}^{3+}$ (aluminum) and the anion is Show more…

Key Concepts

Water of Crystallization

Water of crystallization refers to the water molecules that are chemically combined in a fixed ratio with the anhydrous compound in a crystalline structure. These water molecules are not merely trapped but are integral to the crystal lattice and can be lost upon heating.

Nomenclature of Hydrates

The nomenclature of hydrates involves naming the anhydrous compound first, followed by a numerical prefix indicating the number of water molecules and the word 'hydrate'. For example, two water molecules yield 'dihydrate', six yield 'hexahydrate', and four yield 'tetrahydrate'. This systematic approach clearly communicates the composition of the compound.

Hydrates

Hydrates are crystalline compounds that include water molecules within their solid structure. The water, known as water of crystallization, is integrated into the lattice of the ionic or coordination compound, affecting both its properties and its stoichiometry.
