If 75 mL of a solution made by dissolving 10.0 g of Ba(OH)₂(K_sp = 5.0×10^–3) in 300 mL of water was added to each of the beakers below, which beaker will a precipitate form? What is the identity of the precipitates that formed?

• A. Only beaker (iv) will form a precipitate. The precipitate that will form is Ba(OH)₂
• B. Beaker (i) and beaker (ii) will form a precipitate. The precipitate that will form is Ba(OH)₂ and NaOH
• C. Beaker (iii) and beaker (iv) will form a precipitate. The precipitate that will form is Ba(OH)₂ and BaBr₂
• D. Only beaker (iii) will form a precipitate. The precipitate that will form is Ba(OH)₂
