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 10¯ 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 ☌. Problem #6: The K sp of AgBr is 5.4 x 10¯ 13 at 25 ☌. 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 10¯ 11 K b for NH 3 is 1.77 x 10¯ 5)ġ) Use the acid base data supplied to calculate :Ģ) 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.

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:Īny sodium hydroxide solution greater than 0.33 M will reduce the to less than 1.1 x 10¯ 10 M. What minimum OH¯ 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 10¯ 10 M?
