Method Of Preparation Of Diazoniun Salts

The solubility product $K_%7B%5Ctext%7Bsp%7D%7D$ for $%5Ctext%7BMg(OH)%7D_2$ is given as $1.0%20%5Ctimes%2010%5E%7B-11%7D$ . The dissolution equilibrium for $%5Ctext%7BMg(OH)%7D_2$ is:
$%5Ctext%7BMg(OH)%7D_2%20%5Crightleftharpoons%20%5Ctext%7BMg%7D%5E%7B2%2B%7D%20%2B%202%5Ctext%7BOH%7D%5E-$ The concentration of $%5Ctext%7BOH%7D%5E-$ ions required to precipitate $%5Ctext%7BMg(OH)%7D_2$ can be found by solving for $%5B%5Ctext%7BOH%7D%5E-%5D$ using the equation: $K_%7B%5Ctext%7Bsp%7D%7D%20%3D%20%5B%5Ctext%7BMg%7D%5E%7B2%2B%7D%5D%5B%5Ctext%7BOH%7D%5E-%5D%5E2$ Substitute $%5B%5Ctext%7BMg%7D%5E%7B2%2B%7D%5D%20%3D%200.1%20%5C%2C%20%5Ctext%7BM%7D$ and $K_%7B%5Ctext%7Bsp%7D%7D%20%3D%201.0%20%5Ctimes%2010%5E%7B-11%7D$ : $1.0%20%5Ctimes%2010%5E%7B-11%7D%20%3D%20(0.1)%5B%5Ctext%7BOH%7D%5E-%5D%5E2$ Solving for $%5B%5Ctext%7BOH%7D%5E-%5D$ : $%5B%5Ctext%7BOH%7D%5E-%5D%20%3D%20%5Csqrt%7B%5Cfrac%7B1.0%20%5Ctimes%2010%5E%7B-11%7D%7D%7B0.1%7D%7D%20%3D%20%5Csqrt%7B1.0%20%5Ctimes%2010%5E%7B-10%7D%7D%20%3D%201.0%20%5Ctimes%2010%5E%7B-5%7D%20%5C%2C%20%5Ctext%7BM%7D$ The pOH is
given by:
$%5Ctext%7BpOH%7D%20%3D%20-%5Clog%5B%5Ctext%7BOH%7D%5E-%5D%20%3D%20-%5Clog(1.0%20%5Ctimes%2010%5E%7B-5%7D)%20%3D%205$ Thus, the pH is: $%5Ctext%7BpH%7D%20%3D%2014%20-%20%5Ctext%7BpOH%7D%20%3D%2014%20-%205%20%3D%209$
