The correct order of acidity among the following species is:a)[Na(H2O)...
Acidity of Aquo Complexes
Aquo complexes are formed when metal ions are surrounded by water molecules. They are called aquo complexes because water molecules act as ligands in these complexes. The acidity of these aquo complexes depends on the charge on the metal ion and its size.
Order of Acidity
The order of acidity among the given aquo complexes is determined by the charge on the metal ion. The higher the charge on the metal ion, the more acidic the complex.
The correct order of acidity among the given species is:
[Sc(H2O)6]3 [Ni(H2O)6]2 [Mn(H2O)6]2 [Na(H2O)6]
Explanation
The correct answer is option B, which places [Sc(H2O)6]3 as the most acidic and [Na(H2O)6] as the least acidic. This is because:
1. [Sc(H2O)6]3 has the highest charge (+3) among the given species, making it the most acidic.
2. [Ni(H2O)6]2 and [Mn(H2O)6]2 have a charge of +2 each, making them less acidic than [Sc(H2O)6]3.
3. [Na(H2O)6] has the lowest charge (+1) among the given species, making it the least acidic.
Hence, the correct order of acidity among the given species is option B.
