Aqueous solutions of BiCl3 is Cloudy because of?
Correct answer: B. Hydrolysis
- A. Condensation
- B. Hydrolysis
- C. Reversible reaction
- D. None
Explanation
BiCl3 in aqueous solution undergoes hydrolysis, leading to the formation of insoluble bismuth oxychloride, which causes the solution to appear cloudy. Condensation does not occur in this context as it involves phase changes between gas and liquid. The concept of a reversible reaction does not directly explain the cloudiness. Option 'None' is incorrect because it implies no explanation, whereas hydrolysis clearly accounts for the observed phenomenon.

About Chemical Equilibrium
Reversible reactions reach dynamic equilibrium when forward and reverse rates become equal, and Le Chatelier's principle predicts the effect of changing concentration, pressure or temperature. The chapter also covers solubility product, the common ion effect, buffer action and the conditions used in Haber's process, with equilibrium shifts distinguished from changes in the equilibrium constant.
