Homework Answers
[Be(OH2)4]2+
Here the Be atom is in +2 state and its electronic configuration of Be2+ is 1s2, the available orbitals of Be2+ for coordination with water are 2s and three 2p orbitals. Hence, four water molecules come and coordinate with Be2+ and hence the hydrate has the formula is [Be(OH2)4]2+
[Mg(OH2)6]2+
Here the Mg atom is in +2 state and its electronic configuration of Mg2+ is 1s22s22p6. The available orbitals of Mg2+ for coordination with water are 3s, three 3p and five 3d orbitals. Hence, six water molecules come and coordinate with Mg2+ ion and hence the formula of the hydrate is [Mg(OH2)6]2+. It cannot accomodate more than six water molecules due to steric repulsion.

answer a b or c
Why is the atomic radius of magnesium ion much smaller than that of a neutral charged magnesium atom? (See the atomic radius graph) The magnesium ion's electrons require less space. No electrons are lost, they move to unoccupied spaces about the nucleus. The magnesium ion has fewer principle quantum energy levels, this causes a decrease in atomic radius. The magnesium ion has a higher Z-effective nuclear charge. The magnesium ion has more principle quantum energy...

the hardness of water causes the disolved Ca+2 ion form magnesium carbonate, Mg CO3 which is slightly doluble solids. soaking solid magnesium carbonate in water only yeilds small amounts of free calcium ion that can be captured but still solvated using a chelating milecule called Ethylendiamineteraacetic acid or EDTA. the 2 reactions involved: 1- Mg CO3 ➡ Mg^+2 + CO^-2 keq= 6.8×10^-6 2- Mg^+2 + EDTA ^-4 ➡ MgEDTA ^-2 + CO ^-2 keq= 4.90×10^8 these reactions combine to give...
