What else can I help you with?
Are ligands complex ions?
No, ligands are not complex ions. Ligands are molecules or ions that can donate electrons to form coordinate bonds with a central metal ion to create a coordination complex. In contrast, complex ions are ions formed from a central metal ion bonded to surrounding ligands.
Are complex ions soluble?
Generally, complex ions are soluble in solution because they are formed by the interaction of a metal cation with ligands. These ligands help stabilize the complex ion and prevent it from precipitating out of solution. However, the overall solubility of a complex ion will depend on various factors such as the nature of the ligands and the specific metal ion involved.
How do you write formulas for complex ions?
To write formulas for complex ions, start by writing the symbol of the central metal cation. Then, add the ligands around the central metal cation. Use coordination numbers and oxidation states to balance the charges of the ions within the complex. Finally, enclose the entire complex in square brackets and indicate the charge outside the bracket.
What ion does alizarin detect?
Alizarin detects calcium ions. It forms a red complex with calcium ions, which can be quantified spectrophotometrically.
Identify the reagent that separates fe3 plus?
To separate Fe3+ ions, one can use a reagent like ammonia (NH3) which forms a complex with Fe3+ ions called iron(III) hydroxide. This complex precipitates out of the solution, allowing for the separation of Fe3+ ions from other components in the mixture.
Ions may be described as simple or complex?
In chemistry are known simple ions but also complex ions.

Use coordination numbers and oxidation states to balance the charges of the ions within the complex. Finally, enclose the entire complex in square brackets and indicate the charge outside the bracket.
What causes the colour of complex ions?
The color of complex ions is caused by the absorption of light due to the splitting of the d-orbitals in the transition metals within the ion. This splitting results in different energy levels and leads to absorption of specific wavelengths of light, giving the complex ion its characteristic color.
What ion does alizarin detect?
Alizarin detects calcium ions. It forms a red complex with calcium ions, which can be quantified spectrophotometrically.
Why does the precipitation of copper ion dissolve in excess aqueous ammonia?
Excess aqueous ammonia forms a complex with copper ions called tetraamminecopper(II) complex, [Cu(NH3)4]2+, which is soluble in water. This complex formation reduces the concentration of free copper ions in solution, causing the precipitation of copper ions to dissolve.
What is the complex salts?
A complex salt is the salt of one or more complex ions, the complex part can be cationic or anionic or both such as Ca3[Co(Cl)6]2 the complex part behaves as an anion [Co(NH3)6]Cl3 the complex part behaves as a cation [Co(NH3)6][Co(Cl)6] the both of the anionic and cationic parts of the are formed by complex ions
Why EBT indicator do not form complex with Mg ions?
EBT (Eriochrome Black T) is a metal indicator that forms stable complexes with certain metal ions like Ca^2+ and Mg^2+. In the case of Mg^2+ ions, the complex formed with EBT is not very stable due to the weaker coordinating ability of Mg^2+ compared to other metal ions like Ca^2+. This results in poor formation of complexes between EBT and Mg^2+ ions.
Identify the reagent that separates fe3 plus?
To separate Fe3+ ions, one can use a reagent like ammonia (NH3) which forms a complex with Fe3+ ions called iron(III) hydroxide. This complex precipitates out of the solution, allowing for the separation of Fe3+ ions from other components in the mixture.
Is KMnO4 a coordinate complex?
KMnO4 is an ionic compound with K+ and MnO4- ions. The permanganate, MnO4-, ion can be considered as a coordination complex between Mn7+ and four O2- ions- , with the O2- tetrahedrally coordinated around the manganese .
