Ag2SO4 Precipitation in Mixtures: For Which Of The Mixtures Will Ag2so4 S Precipitate
The solubility of Ag2SO4 in water is crucial in determining whether it will precipitate out of a solution when mixed with other substances. This article explores the factors affecting Ag2SO4 solubility, the mixtures in which it precipitates, and its applications.
Ag2SO4 Solubility
Ag2SO4 is a sparingly soluble salt with a solubility of 0.051 g/100 mL at 25 °C. This means that only a small amount of Ag2SO4 can dissolve in water at a given temperature.
| Temperature (°C) | Solubility (g/100 mL) |
|---|---|
| 0 | 0.044 |
| 10 | 0.047 |
| 20 | 0.050 |
| 25 | 0.051 |
| 30 | 0.053 |
Factors Affecting Ag2SO4 Solubility
The solubility of Ag2SO4 is influenced by several factors, including:
- Common Ion Effect:The presence of common ions (Ag+ or SO42-) in the solution reduces the solubility of Ag2SO4 due to the formation of less soluble complexes.
- Temperature:The solubility of Ag2SO4 increases slightly with increasing temperature, as the solvent molecules become more energetic and can break apart the crystal lattice more effectively.
- pH:The pH of the solution affects the solubility of Ag2SO4 indirectly. In acidic solutions, the formation of HSO4- ions reduces the concentration of free SO42- ions, leading to increased solubility. In basic solutions, the formation of AgOH complexes reduces the concentration of free Ag+ ions, also leading to increased solubility.
Mixtures and Ag2SO4 Precipitation
Ag2SO4 will precipitate out of a solution when its solubility is exceeded. This can occur when:
- A solution containing Ag+ and SO42- ions is mixed with a solution containing a common ion (Ag+ or SO42-).
- The temperature of a saturated solution of Ag2SO4 is decreased.
- The pH of a solution containing Ag+ and SO42- ions is adjusted to a value that reduces the solubility of Ag2SO4.
| Mixture | Expected Precipitation |
|---|---|
| AgNO3 + Na2SO4 | Yes |
| AgCl + H2SO4 | Yes |
| AgNO3 + NaCl | No |
| Ag2SO4 + H2O | No |
