Several reactions are carried out using Agr, a cream-colored silver salt for which the value of the solubility product constant, Kap, is 5.0 x 10^-13 at 298 K
a. Write the expression for the solubility product constant, Ksp, of AgBr
b. Calculate the value of (Ag) in 50.0 mL of a saturated solution of AgBr at 298 K
c. A 50.0 ml. sample of distilled water is added to the solution described in part (b), which is in a beaker with some solid AgBr at the bottom. The solution is stirred and equilibrium is reestablished. Some solid AgBr
remains in the beaker. Is the value of Ag greater than, less than, or equal to the value you calculated in part (b)? Justify your answer
d. Calculate the minimum volume of distilled water, in liters, necessary to completely dissolve a 5.0 g sample of AgBr(s) at 298 K. (The molar mass of AgBr is 188 g mol)
e. A student mixes 10.0 mL of 1.5 x 10^-4 MAgNO3 with 2.0 mL of 5.0 x 10^-“4 M NaBr and stirs the resulting mixture. What will the student observe? Justify your answer with calculations
f. The color of another salt of silver, Ag(s), is yellow. A student adds a solution of Nal to a test tube containing a small amount of solid, cream-colored AgBr. After stirring the contents of the test tube, the student
observes that the solid in the test tube changes color from cream to yellow
Write the chemical equation for the reaction that occurred in the test tube
Which salt has the greater value of Ksp: AgBr or AgI? Justify your answer
