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
And the answer choices,
1 M HNO3
1 M NaNO3
None of these choices.
1 M HCl
1 M NaCl
