Consider the following reaction in equilibrium and tell addition of which chemical will turn the cloudy solution into clear solution?BiCl3+H2O...>BiOCl+2HCl
Correct answer: D. HCl
- A. BiCL3
- B. H2O
- C. BiOCI
- D. HCl
Explanation
If you want to turn the cloudy solution (which indicates the presence of BiOCl) into a clear solution, you can add an excess of HCl. This addition will cause the equilibrium to shift to the right, reducing the amount of BiOCl and potentially dissolving it, thereby clarifying the solution.

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.
