Several reactions are carried out using AgBr, a cream-colored silver salt for which the value of the solubility product constant, Ksp, is 5.0 x 10⁻¹³ at 298 K.
a) Calculate the value of [Ag+] in 50.0 mL of a saturated solution of AgBr at 298 K.
b) 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 re-established. 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
c) Calculate the minimum volume of distilled water, in liters, necessary to completely dissolves a 5.0 g sample of AgBr at 298 K.
d) A student mixes 10.0 mL of 1.5x10⁻⁴ M AgNO₃ with 2.0 mL of 5.0x10⁻⁴ M NaBr and stirs the resulting mixture. What will the student observe?
