Potash alum (KAl(SO4)2·12H2O) has a higher vant Hoff factor value in aqueous solution compared to the other compounds mentioned. The vant Hoff factor (i) is a measure of the extent to which a compound dissociates into ions when dissolved in a solvent. It is equal to the ratio of moles of particles in solution to moles of solute dissolved.
Potash alum is a hydrated double salt of aluminum sulfate and potassium sulfate. It dissociates in water to release aluminum ions (Al3+), potassium ions (K+), sulfate ions (SO42-), and water molecules (H2O).
On the other hand, Mohr's salt (Fe(NH4)2(SO4)2·6H2O), potassium ferrocyanide (K4[Fe(CN)6]), and carnalite (KCl·MgCl2·6H2O) have lower vant Hoff factor values in aqueous solution.
- Mohr's salt: Mohr's salt is a hydrated double salt of iron(II) sulfate and ammonium sulfate. It dissociates in water to release iron(II) ions (Fe2+), ammonium ions (NH4+), sulfate ions (SO42-), and water molecules (H2O). Since it has fewer ions in solution compared to potash alum, its vant Hoff factor value is lower.
- Potassium ferrocyanide: Potassium ferrocyanide is a coordination compound. It dissociates in water to release potassium ions (K+), ferrocyanide ions ([Fe(CN)6]4-), and water molecules (H2O). Again, it has fewer ions in solution compared to potash alum, resulting in a lower vant Hoff factor value.
- Carnalite: Carnalite is a mineral composed of potassium chloride and magnesium chloride hexahydrate. When dissolved in water, it releases potassium ions (K+), magnesium ions (Mg2+), chloride ions (Cl-), and water molecules (H2O). Similar to the previous compounds, it has fewer ions in solution and therefore has a lower vant Hoff factor value.
Potash alum has a higher vant Hoff factor value because it dissociates into a greater number of ions in aqueous solution compared to the other compounds mentioned. This is due to its unique structure as a double salt, which contains multiple ions. As a result, it has a higher conductivity and greater colligative properties, such as boiling point elevation and freezing point depression, when dissolved in water.
In summary, the higher vant Hoff factor value of potash alum in aqueous solution compared to Mohr's salt, potassium ferrocyanide, and carnalite is attributed to its greater dissociation into ions.
