Question

(a) Write a balanced chemical equation that shows dissolving AgCl(s) in water.

(b) Write K expression for (a). Note this K is also called Ksp AgCl(s)!!!

(c) AgCl according to solubility rule is insoluble. Knowing this, do you expect Ksp to be large or small? Explain.

(d) Draw an ICE table for the equation you have for (a). Assume you have “some” AgCl(s), fill in the ICE table, and show how it relates to Ksp. Do not solve for anything.

(e) Give formal definition for “solubility”. Give three possible units for solubility.

(f) From ICE table you have for (d), find where definition of ‘solubility’ matches. Mark it in ICE table in (d) or describe it here.

Answer 1

answer of a and b

c) As AgCl is sparingly soluble salt ( insoluble) , K_sp is very small.

d)

e)

Solubility is a degree which measures the maximum amount of a substance can dissolve in a certain amount of solvent to make a saturated solution in a certain temperature and pressure.

According to IUPAC , solubility is the analytical composition of a solution in saturated state. It is expressed as poportion of a solute in solvent.

units of solubility are molarity ( mole/L) , molality, mole fraction .

f) Solubility of AgCl is equal to the concentration of Ag⁺ or Cl^- at equilibrium .
