The Salts X(NO₃)₂ and Y(NO₃)₂ (Where X⁺ and Y⁺ Are

question 109

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 K_sp values listed below, decide which aqueous reagent, if any, will definitely precipitate X⁺ before precipitating Y⁺ from solution. Given K_sp values: XCl₂, 1 * 10¯⁵; YCl₂, 1 * 10¯¹⁰; X(OH) ₂, 1 *10¯¹⁰; Y(OH) ₂, 1 * 10¯⁵

• A) 1 M NaNO₃
• B) 1 M HCl
• C) 1 M HNO₃
• D) 1 M NaCl
• E) None of these reagents will accomplish the precipitation.
