16 A) Mg(OH)2 is a sparingly soluble compound, in this case a base, with a solubility product, Ksp, of 5.61×10−11. It is used to control the pH and provide nutrients in the biological (microbial) treatment of municipal wastewater streams.Based on the given value of the Ksp, what is the molar solubility of Mg(OH)2 in pure H2O? Answer is molar solubility = 2.41×10−4 M 16 B) Based on the given value of the Ksp, what is the molar solubility of Mg(OH)2...
What is the concentration of M2+ in a saturated solution of a metal hydroxide M(OH)2 (assume Ksp = 1.8 x 10-16) in an aqueous buffer of pH = 8.3? -The answer I got was 4.5e-5 M. Just wanted to confirm this was correct, thank you!
