Enhancing the solubility
The solubility of a substance means the ability to mix with another substance in a homogenous way. Mineral salts dissolve in water differently. The extent of solubility ranges widely, from poorly soluble (< 0.1 mol/l), to medium soluble (0.1 to 1 mol/l) and slightly soluble salts (>1 mol/l).
Highly concentrated solutions enhance their efficiency
Many technical processes in which salt solutions are used run more efficient, if the used solution has a high concentration.
In addition, the application of certain salts helps to make processes less dangerous. Iron Nitrate is a good water-soluble salt, used for example in the production of iron catalysts. However, the formation of nitrous gases is a serious health hazard. The use of a non-hazardous cation like Citrate would be a safe alternative, but posses the difficulty that Ferrous Citrate is considerably less water-soluble than Ferrous Nitrate.
Salts dissolve salts – the salting-out effect
In order to reach a high salt concentration, one can take advantage of the so-called salting-out effect. Certain anions often increase the solubility of other mineral salts in a medium.
Using the well-soluble double salt of Ammonium Iron (III) Citrate you can increase the solubility of only 4g / l to 350g / l!
Furthermore, the solubility of other salts which are difficult to soluble can be increased significantly with the help of solubility agents. We can offer you Lithium, Potassium, Sodium or Ammonium Citrate:
| Product |
Solubility |
| Copper (II) Citrate | 0,02 g/l |
| Copper (II) Citrate with Sodium Citrate | 60 g/l |
| Aluminium Lactate | 17 g/l |
| Aluminium Lactate with Sodium Lactate |
30 g/l |
In close cooperation with you we can also develop your individual combinations.
