A solution required `[OH^(-)]=2M`. If degree of dissociation of `Mg(OH)_(2)` is `alpha`, what analytical molarity solution of `Mg(OH)_(2)` isA. `alpha`B. `2 alpha`C. `(1)/(2alpha)`D. `(1)/(alpha)` |

Answer» Correct Answer - D `[OH^(-)]=2M` `{:(Mg(OH)_(2)hArr,Mg^(2+)+,2OH^(-),,),(C,0,0,,),(C(1-alpha),Calpha,2Calpha,,):}` `:. 2 Calpha=2M` `:. C=(2)/(2 alpha)=(1)/(alpha)` |
