A. The solubility of silver sulfate,Ag2SO4 , in water has been determined to be 8.00 g/L. What is the solubility of silver sulfate in 0.350 M of sodium sulfate,NA2SO4 NA2 ? B. Barium sulfate is often used as a test for barium ion in qualitative analysis. Using the solubility product constant (KSP = 1.1X ten to the negative tenth power. ), calculate the molar solubility of barium sulfate in water C. What is the solubility of magnesium hydroxide in a solution buffered at pH 8.65? KSP = 1.8x ten to the negative 11th power?
