举一反三
- The solubility of an insoluble compound is independent of the ionic strength of the solution.
- Increasing the ionic strength of the solution will reduce the conditional potential of the Fe3+/Fe2+ couple.
- Increasing ionic strength would compress the electric double layer and increase the stability of the colloid。 （ ）
