Interested in participating in Relay for Life? This year marks the American Cancer Society’s 25 th Relay anniversary and is RPI’s 4 th Relay for Life! This year’s Relay is being held Friday, April 17 th , from 6pm to 6am April 18 th on the ‘86 Field. The Rensselaer Chemistry Society is also welcoming any members to their team, Flubber . (They will also be making flubber during Relay in honor of the movie!) If you’re interested in joining the team (or just want information about the event), please contact Kathleen rd

Unformatted text preview: + when 25.0mL each of 0.044M AgNO 3 and 0.57M Na 2 S 2 O 3 are mixed? K f of Ag(S 2 O 3 ) 2 3-= 4.7 x 10 13 The solubility product of AgIO 3 is 4.5 x 10-8 . When excess solid AgIO 3 is treated with 1.0L of 1.0M NH 3 , 85g of AgIO 3 dissolves. AgIO 3 (s) + 2NH 3 (aq) Ag(NH 3 ) 2 + (aq) + IO 3-(aq) Calculate the equilibrium constant for the following reaction: Ag(NH 3 ) 2 + (aq) Ag + (aq) + 2NH 3 (aq) The solubility product for PbCl 2 is 2 x 10-5 . If 0.50g of solid PbCl 2 is added to 300.mL of water, will all of the solid dissolve? Part A: Determine the mass of Na 2 CO 3 and the volume of 0.500M HCl solution required to make 1.5L of a buffer solution at pH = 9.85 and at a total concentration of 0.350M. Part B: How many grams of NaOH must be added to the buffer from Part A to change the pH by 0.15 units? After this NaOH has dissolved, is the solution still a buffer?...
