FAQs on Difference Between Double Salt & Complex Video Lecture - Chemistry Class 12 - NEET

1. What is the difference between double salt and complex?
Ans. Double salts are compounds formed by the combination of two different salts, while complexes are compounds formed by the coordination of a metal ion with one or more ligands. In double salts, the two salts retain their individual identities, whereas in complexes, the ligands bind to the metal ion and form a coordination sphere.
2. How are double salts and complexes different in terms of their composition?
Ans. Double salts are composed of two different salts, where each salt retains its individual chemical formula and crystal structure. On the other hand, complexes consist of a central metal ion bonded to one or more ligands, where the overall composition and structure of the complex are different from the individual components.
3. Can double salts be converted into complexes or vice versa?
Ans. Yes, double salts can be converted into complexes by replacing one of the salt components with a ligand that coordinates to the metal ion. Similarly, complexes can be dissociated to form double salts by releasing the ligands and allowing the metal ion to combine with a different salt component.
4. What is the role of ligands in complex formation?
Ans. Ligands play a crucial role in complex formation as they bond to the central metal ion through coordinate covalent bonds. They provide additional stability to the complex and influence its physical and chemical properties, such as color, reactivity, and solubility.
5. Are there any examples of double salts and complexes commonly encountered in everyday life?
Ans. Yes, there are several examples of double salts and complexes that we encounter in everyday life. Some examples of double salts include alum (potassium aluminum sulfate), Mohr's salt (ammonium iron(II) sulfate), and Rochelle salt (potassium sodium tartrate). Examples of complexes include hemoglobin (a complex of iron with oxygen-binding ligands in blood), chlorophyll (a complex of magnesium with porphyrin ligands in plants), and vitamin B12 (a complex of cobalt with various ligands in the human body).
