question 44

Multiple Choice

A solution is prepared by mixing 50.0 mL of 0.50 M Cu(NO₃) ₂ with 50.0 mL of 0.50 M Co(NO₃) ₂. Sodium hydroxide is added to the mixture. Which hydroxide precipitates first and what concentration of hydroxide ions present in solution will accomplish the separation? K_sp = 2.2 *10¯²⁰ for Cu(OH) ₂, K_sp = 1.3 *10¯¹⁵ for Co(OH) ₂

• A) Co(OH)₂; [OH¯] = 6.9 * 10¯⁶ M
• B) Co(OH)₂; [OH¯] = 2.6 * 10¯⁷ M
• C) Cu(OH)₂; [OH¯] = 1.8 * 10¯⁷ M
• D) Cu(OH)₂; [OH¯] = 1.1 * 10¯⁹ M
• E) Cu(OH)₂; [OH¯] = 1.0 * 10¯¹⁷ M
