Explain agcl is a sparingly soluble salt

Reference no: EM13228255

1. AgCl is a sparingly soluble salt, with a solubility of about 10-5 M in pure water. Adding KCN increases the solubility of AgCl because:

CN- reacts with Ag+ to make a soluble complex.
CN- is a base, which increases the pH to form soluble AgOH.
K+ reacts with Cl- to form solid KCl.
CN- reduces Ag+ to Ag metal.
CN- reacts with Ag+ to make a sparingly soluble salt with a larger Ksp than AgCl.

2. Which of the following substances, when added to a saturated solution of AgCO3, will increase the solubility of AgCO3 in the solution?
1. Na2CO3
2. AgNO3
3. HCl
4. NH3
