Ferric oxide (Fe2O3) is not soluble in water.
To distinguish between sodium sulfate and ammonium sulfate, you can add barium chloride (BaCl₂) solution to the samples. Sodium sulfate will not produce any precipitate, while ammonium sulfate will give a white precipitate of barium sulfate (BaSO₄). For differentiating ferric salt from ferrous salt, adding potassium thiocyanate (KSCN) to a ferric salt solution will produce a blood-red complex (ferric thiocyanate), while ferrous salt will not produce this color change.
When ferric sulfate is mixed with sodium hydroxide, a red-brown precipitate of iron(III) hydroxide is formed, along with the formation of water as a byproduct. The reaction is strongly exothermic. This precipitate is insoluble in water and can easily be seen as a solid settling at the bottom of the reaction mixture.
When barium chloride solution is combined with sodium sulfate solution, a white precipitate of barium sulfate is formed. This is because barium sulfate is insoluble in water and therefore precipitates out of the solution. This reaction is used to detect the presence of sulfate ions in a solution.
When sodium sulfate is mixed with water, it dissolves to form a clear, colorless solution. Sodium sulfate is highly soluble in water, so it easily breaks down into its ions, sodium (Na+) and sulfate (SO4 2-), which become dispersed in the water.
If the sodium sulfate and barium nitrate are both in solution in water, a precipitate of barium sulfate will be formed, because this salt is much less soluble in water than barium nitrate, sodium sulfate, or sodium nitrate.
One common method to test for sodium sulfate is by performing a precipitation reaction. Mixing a solution of sodium sulfate with a solution of barium chloride will result in the formation of a white precipitate of barium sulfate. The presence of this precipitate confirms the presence of sulfate ions, indicating the presence of sodium sulfate in the original solution.

Sodium sulfate dissolves in water to produce a solution of sodium sulfate.
When copper sulfate and sodium hydroxide are mixed together, a double displacement reaction occurs. The copper ions from copper sulfate react with hydroxide ions from sodium hydroxide to form a blue precipitate of copper hydroxide. The resulting solution will contain sodium sulfate.

When strontium chloride and sodium sulfate are mixed, a double displacement reaction occurs. The strontium cations (Sr2+) combine with sulfate anions (SO4 2-) to form strontium sulfate (SrSO4), which is insoluble and precipitates out of the solution as a solid. Sodium cations (Na+) combine with chloride anions (Cl-) to form sodium chloride (NaCl), which remains dissolved in the solution.
The color of a sodium sulfate solution in water is colorless. Sodium sulfate is a white and crystalline solid that dissolves in water to form a clear and colorless solution.
