How do the concentrations of Ag+ and SO42- change when more solid Ag2SO4 is added to the already saturated solution?
How do the concentrations of Ag+ and SO42- change when more solid Ag2SO4 is added to the already saturated solution?
A solution is saturated with silver sulfate and contains excess solid silver sulfate: Ag2SO4(?) ⇌ 2Ag + (??) + SO4^2- (??) A small amount of solid silver sulfate containing a radioactive isotope of silver is added to this solution. Within a few minutes, a portion of the solution phase is sampled and tests positive for radioactive Ag+ ions. Explain this observation.
What will happen when solid Ag is added to a 1.0 M CuBr2 solution? Brą () + 2 e 2 Br E = 1.09 V ---- Ag (5) E° -0.80 V Cu + 2 e ---> Cu (s) = 0.34 V Select one or more: a. Nothing happens b. The Ag dissolves c. Cu (s) is produced d. Brą is produced
Problem 2: Find the concentrations of Ag, CN, and HCN in a saturated solution of AgCN whose pH is somehow fixed at 9.00. Consider the following equilibria: Ksp = 2.2 x 10-16 AgCN(s) CN + H20 Ag+ + CN- HCN(aq) + OH- Kb = 1.6 x 10-5
Solid NaI is slowly added to a solution that is 0.010 M in Cu+ and 0.010 M in Ag+.(a) Which compound will begin to precipitate first?(b) Calculate [Ag+] when CuI just begins to precipitate.(c) What percent of Ag+ remains in solution at this point?
Solid Nal is slowly added to a solution that is 0.0081 M Cu+ and 0.0099 M Ag+. Which compound will begin to precipitate first?Calculate [Ag+] when Cul just begins to precipitate. What percent of Agt remains in solution at this point?
"calculate the concentration of Ag+ present in a solution at equilibrium when concentrated ammonia is added to a 0.010m solution of AgNO3 to give an equilibrium concentration of (NH3)= 0.20 m. Neglect the small volume change that occurs when NH3 is added
A saturated solution of BaSO4 is made by dissolving excess solid BaSO4 in a 1 L solution of 0.20 M Na2SO4. How many grams of BaSO4 will dissolve in the 1.0 L volume? Assume the volume does not change when the solid is added. Ksp = 1.1 x 10-10. (A) 2. 85 x 10-7 (B) 2. 93 x 10-7 (C) 3.02 x 10-7 (D) 3. 18 x 10-7 (E) 1.28 x 10-7 Submit
1. How do you know when a solution is saturated?
A) 10x10 mol/L of BaCl2 are added to a saturated BaSO4 solution. Given that the solubility product constant of barium sulfate is 1.2x10-10 find the equilibrium concentrations of Ba2+ and SO42- ions after the addition of BaCl2. B) The pH of an originally acidic solution containing 10-3 CaCl2 and 10-1 M oxalic acid (H2C204) is raised slowly. At what pH value will calcium oxalate (CaC204) first precipitate? ( Assume that CaCl2 completely dissociates into its constituent ions) Ksp (Ca C204)...
How does the molarity change if the volume is constant but more solute is added? Molarity (M) = moles solute liter solution 1. Select cobalt(II) nitrate from the pull-down menu, and select "show values". Adjust the solute and solvent amounts and record the results in the table below. Hitting the reset button will return the solute and solution volume sliders to 0.500 moles and 0.500 L, respectively. Complete the table. Cobalt(11) nitrate Solute Amount Solution Volume Molarity 0.500 mol 0.500...
