Question | Answer |
Molar solubilities can be calculated using? | Ksp |
Ksp can be used to determine, if a precipitate will form in a solution. For this, the value of the ion product Q is used. how does Q correlate to Ksp? | Q > Ksp Precipitate will form Q = Ksp No precipitate Q < Ksp No Precipitate |
selective precipitation | forming insoluble compounds with one metal ion or a group of metal ions under conditions, under which other metal ions do not form insoluble compounds and stay in solution. |
Complex ions consist of? | Ligands- which can be neutral molecules with lone-pairs, or anions. Donor atoms- the atoms in the ligands that provide the electrons forming the bond. |
The formation of a complex ion is...? | The formation of a complex ion is a reaction, in which one ligand, e. g. water, is replaced by another ligand. Leaving out water simplifies the equation, the equilibrium can be describes using a formation constant Kform. |
