1.A 25.0 L solution is made of 0.10 M acid and 0.13 M conjugate base. What mass of HNO3 (MM = 63.01) in grams can the buffer absorb before one of the components is no longer present?
2. If 147 g of ZnF2 (Ksp=0.0300) is added to water to make a 1.00 L to the solution, what is the [F-] concentration in the solution in molarity?
3. A solution begins with .100M of NaF dissolved in water. What is the concentration of Magnesium ion in the solution, if MgF2 was added in excess? Ksp (MgF2)= 5.2*10^-11
