Finding dissolved amount of base from pH and solubility product
Calculate the amount of $\ce{Mg(OH)2}$ which is solubilized in $\pu{1.25 L}$ of a buffered solution at $\mathrm{pH} = 9.5$. $(K_\mathrm{sp}(\ce{Mg(OH)2}) = \pu{5.61E-12})$.
From $\mathrm{pH}$ I ...

What is total concentration of buffer used in derivation of buffer capacity?
ChemBuddy — The buffer capacity provides the following:
$$\ce{HA <=> H+ + A-}$$
Total concentration of the buffer $c_\mathrm{buf}$ is given by
$$c_\mathrm{buf} = [\ce{HA}] + [\ce{A-}]\tag{19.3}$...
