Multiple Choice
The salts X(NO3) 2 and Y(NO3) 2 (where X+ and Y+ are metal ions) are dissolved in water to give a solution which is 0.1 M in each of them. Using the Ksp values listed below, decide which aqueous reagent, if any, will definitely precipitate X+ before precipitating Y+ from solution. Given Ksp values:
XCl2, 1 × 10-5 YCl2, 1 × 10-10 X(OH) 2, 1 × 10-10 Y(OH) 2, 1 × 10-5
A) 1 M NH3
B) 1 M HCl
C) 1 M HNO3
D) 1 M NaCl
E) None of the above reagents will accomplish the precipitation.
