Solubility product with Cobra4
The solubility of poorly soluble salts is expressed as the solubility product, i.e. the product of the concentration of cations and anions in the solution which are in equilibrium with the solid salt. These concentrations can be determined via conductivity measurements.
- Good and reproducible results due to temperature control in the experiment.
- The use of the compact Cobra4 Mobile-Link is space-saving.
