In a magnesium oxide unit, the distance between the magnesium ion (Mg2+) and the oxide ion (O2−) is 2.07×10-10 m. Calculate the work required to separate the two ions to an infinite distance apart. (Model the ions as point charges at rest before and after the separation.)
In a magnesium oxide unit, the distance between the magnesium ion (Mg2+) and the oxide ion (O2−) is 1.81×10-10 m. Calculate the work required to separate the two ions to an infinite distance apart. (Model the ions as point charges at rest before and after the separation.)
In a magnesium oxide unit, the distance between the magnesium ion (Mg2+) and the oxide ion (O2−) is 2.13×10-10 m. Calculate the work required to separate the two ions to an infinite distance apart. (Model the ions as point charges at rest before and after the separation.) If you could do this without using Calculus that would be great.

The magnesium and calcium ions present in seawater ([Mg2+] = 0.059 M and [Ca2+] = 0.011 MM) can be separated by selective precipitation with KOH. Part A If the concentration of Mg2+ in the solution were 0.036 M, what minimum [OH−] triggers precipitation of the Mg2+ ion? (Ksp=2.06×10^−13) Express your answer to two significant figures and include the appropriate units.
