Common ion effect on solubility pogil worksheet

We begin by setting up a table to help us keep track of the concentrations of P b 2+ and IO 3 вЂ“ in this system. Knowing what answers are reasonable will help you spot errors in your calcula- tions and give you more confidence that your solution to a problem is correct. How is the solubility of Pb(IO 3) 2 affected if we add Pb(IO 3) 2 to a solution of 0.10 M Pb(NO 3) 2? Before we set up and solve the problem algebraically, think about the chemistry occurring in this system, and decide whether the solubility of Pb(IO 3) 2 will increase, decrease, or remain the same. Lem since the dissolution of the solid is the only source of Pb 2+ or IO 3 вЂ“. In other words, the ignoring was a perfectly valid thing to do.A More Complex Problem: The Common Ion EffectД¬alculating the solubility of Pb(IO 3) 2 in distilled water is a straightforward prob. Substituting into a quadratic solver gives: If you decided that the additional amount of silver ion CANNOT be ignored, you would have this: To two significant digits, the bromide concentration is 1.1 x 10ВЇ 11 mol/L This value is small compared to 0.050 M, it can be ignored. The solution will also contain additional Ag +, due to the dissociation of the AgBr. The solution already contains 0.050 M Ag + from the dissociation of the AgNO 3. Calculate the molar solubility of AgBr in 0.050 M AgNO 3(aq) at 25 вЊ. Problem #6: The K sp of AgBr is 5.4 x 10ВЇ 13 at 25 вЊ. Problem #5 - Part 3: Calculate the molar solubility of Cr(OH) 3 in a solution buffered at pH = 11.00

Q is a 'reaction quotient.' You might have to look that up. Problem #5 - Part 2: 4.0 x 10 -4 g of NaOH is added. Problem #5: 1.1 x 10 -4 g of Cr(OH) 3 is added to 120. Problem #4: What is the maximum concentration of Mg 2+ ion that can remain dissolved in a solution that contains 0.7147 M NH 3 and 0.2073 M NH 4Cl? (K sp for Mg(OH) 2 is 1.2 x 10ВЇ 11 K b for NH 3 is 1.77 x 10ВЇ 5)ДЎ) Use the acid base data supplied to calculate :Дў) Use the K sp expression to calculate the : Since we were asked for the moles of silver chromate that would disolve in 1.00 L, the final answer is: Since there is a 2:1 ratio between the moles of aqueous silver ion and the moles of silver chromate that dissolved, 1.5 x 10 -5 M is the molar solubility of Ag 2CrO 4 in 0.010 M K 2CrO 4 solution. K sp for Ag 2CrO 4 = 9.0 x 10 -12.ДЎ) Concentration of dichromate ion from potassium chromate: Problem #3: Calculate the number of moles of Ag 2CrO 4 that will dissolve in 1.00 L of 0.010 M K 2CrO 4 solution. Note how zinc hydroxide would precipitate even when the solution is slightly acidic. X = 5.91657 x 10 -8 M (I kept a few guard digits.) Problem #2: Calculate the pH at which zinc hydroxide just starts to precipitate from a 0.00857 M solution of zinc nitrate. Substituting into the K sp expression:ДЄny sodium hydroxide solution greater than 0.33 M will reduce the to less than 1.1 x 10ВЇ 10 M. What minimum OHВЇ concentration must be attained (for example, by adding NaOH) to decrease the Mg 2+ concentration in a solution of Mg(NO 3) 2 to less than 1.1 x 10ВЇ 10 M? Problem #1: The solubility product of Mg(OH) 2 is 1.2 x 10ВЇ 11. The Common Ion Effect - Problems 1 - 10 The Common Ion Effect
