Answer to Problem 23CR
The expression of Ksp for Cu(OH)2(s) is,
Ksp=[Cu2+][OH−]2.
Explanation of Solution
The given sparingly soluble substance is Cu(OH)2(s). On dissolution in water, salts dissociate to form metallic cations and hydroxide anions. The dissociation reaction of Cu(OH)2(s) is,

Hello, I am doing a court case analysis in my Analytical Chemistry course.
The case is about a dog napping and my role is prosecution of the defendant.
I am tasked in the Area of Expertise in Neutron Activation and Isotopic Analysis.
Attached is the following case study reading of my area of expertise!
The landscaping stone was not particularly distinctive in its decoration but matched both the color and pattern of the Fluential’s landscaping stone as well as the stone in the back of the recovered vehicle. Further analysis of the stone was done using a technique called instrumental neutron activation analysis. (Proceed to Neutron Activation data)
Photo Notes: Landscaping stone recovered in vehicle. Stone at Fluential’s home is similar inappearance.
Finally, the white paint on the brick was analyzed using stable isotope analysis. The brick recovered at the scene had smeared white paint on it. A couple of pieces of brick in the back of the car had white paint on them. They…
