use the Ksp of SnS2= 1.0X10^-70 and calculate the pH of a hydrogen sulfide solution needed to precipitate 99.99% of the tin(IV) ion assuming [Sn^4+]=0.05M and that [H2S]=0.10M.
If 29.0 mL of 0.10 M Ba(NO3)2 are added to 76.0 mL of 0.21 M Na2CO3, will BaCO3 precipitate? Calculate Q
A solution containing Pb2+ and a solution containing IO3- are poured together and quickly mixed. After mixing, the solution contains 0.0030 M Pb2+ and 0.040 M IO3-. Immediately Pb(IO3)2(s), which has Ksp=2.510-13, begins to precipitate. Calculate the free concentrations of Pb2...
What concentration of chloride ion is required to precipitate 99.9% of the lead ion from a solution with [Pb^2+]= 0.045 mol/L ?
Let's explore the efficiency of chloride ion precipitation in seperating Ag^+ from Pb^2+ in a solution. Suppose that [Pb^2+]= 0.045 mol/L and [Ag^+]= 0.084 mol/L. Calculate the chloride ion concentraion required to just start precipitation of Pb^2+ ion and then calculate t...
A container is charged with hydrogen, nitrogen, and ammonia gases at 120°C and the system was allowed to reach equilibrium. What will happen if the volume of the container is increased at constant temperature? 3H2(g) + N2(g) 2 NH3(g)
Consider the following equilibrium reaction: NaHCO3(s) Na2CO3(s) + H2O(g) + CO2(g) When 100 g of sodium hydrogen carbonate are added to a reaction vessel, the temperature is increased to 200°C, and the system comes to equilibrium. What happens to the partial pressure of ca...
