1. Silver nitrate is added to a saturated AgCl so lut ion unt il the [Ag ] = 0.10 M. What will be the – −10 [Cl ] remaining in so lution? (Ksp AgCl = 1.7 x 10 ) Ksp = +
[Ag ] = After AgNO3 has been added –
[Cl ] = 2
2. 0.010 mo l of Na2CrO4 is added to 1.0 L of saturated BaCrO4 solut ion. What is the [Ba + ]? – (Ksp BaCrO4 = 8.5 x 10 11) ˆˆ
