E. None of the above

Select one:

a. Only E; Only B and C

b. Only B and C; Only A

c. Only A; Only B and C

Answer 1

Hi there,

Correct option: a. Only E; Only B and C

Q: Which of the following would decrease the Ksp for AgCl?

Answer: E. None of the above, the Ksp of a compound is constant at constant temperature.

Q: Which of the following would decrease solubility of AgCl?

AgCl <==> Ag+ + Cl-

Adding AgNO3 increases the Ag+ concentration and also adding NaCl increases the Cl- concentration will shift equilibrium towards left hence solubility decreases.

Answer:

B. Adding a solution of AgNO3

C. Adding a solution of KC

Hope this helped you!
