Example #1: Determine the K sp of silver bromide, given that its molar solubility is 5.71 x 10¯ 7 moles per liter. Set up an ICE table - two AgCN react to form one Ag+ and one [Ag(CN)2]- - and solve for x = [Ag+]. I'm stuck at the ICE table you told me to do, as I don't know how to do it without a means of getting the concentration, unless I'm missing something. The Solubility Product For Ni(OH)2(s) Is 1.6 10−16. Press question mark to learn the rest of the keyboard shortcuts. Learning Objectives. (3) You have two equilibria going on here.AgCN = Ag+ + CN- (Ksp)andHCN = H+ + CN- (Ka), Add the first and the reverse of the second together to get:AgCN + H+ = Ag+ + HCN (Keq = Ksp*(1/Ka) = Ksp/Ka). Thank you. 16 - Silver chloride dissolves readily in 2 M NH3 but... Ch. Calcium hydrogen phosphate 2) The K sp expression is: K sp = [Ag +] [Br¯]. Silver nitrite AgNO 2 6.0×10 –4. Identification Product Name Silver cyanide Cat No. Now let's think about why. Silver iodate AgIO 3 3.0×10 –8. Compare the effects on the solubility of silver cyanide by addition of HNO 3 (aq) or by addition of NH 3 (aq). When 1.5 x 10^-8 moles of AgCN dissolve in a liter of water, then, by the above equation, it produces 1.5 x 10^-8 moles of Ag+ and the same amount of CN-. The solubility of silver chloride is 1.9 ( 10–3 g/L. cyanide ion. 73 . Will a precipitate for when 100.0ml of 4.0 x 104M magnesium nitrate is added to 100.0ml of 2.0 x 104M sodium hydroxide?
