For each of the salts on the left, match the salts on the right that can be compared directly, using Ksp values, to estimate solubilities. If more than one answer is correct, enter the letters without delimiting characters: 1. barium sulfate A. Mg(OH)2 2. lead fluoride B. NiS C. BaCrO4 D. Mn(OH)2
Write the expression for Ksp in terms of the solubility, $, for each salt when dissolved in water: barium sulfate, lead fluoride.
Note: Multiply out any number and put it first in the Ksp expression. Combine all exponents for $_ Ksp.
