Question

The molecular formula of magnesium acetate is:
A. $Mg(C{H_3}CHOO)$
V. $M{g_2}{(C{H_3}COO)_3}$
C. $Mg{(C{H_3}COO)_2}$
D. $Mg{(C{H_3}COO)_3}$

Answer 1

Hint: The magnesium acetate is generally the magnesium salt of the acetic acid. Oxidation state of Magnesium ($Mg$ ) is + 2 and the oxidation state of acetate ion ${(C{H_3}COO)^ - }$ is -1 .

Step by step answer: Magnesium Acetate is the acetate salt form of magnesium ($Mg$ ). Magnesium ($Mg$ ) is a divalent cation and acetate ${(C{H_3}COO)^ - }$ is anion with -1 charge. So according to the given information the molecular formula of magnesium acetate must be $Mg{(C{H_3}COO)_2}$ .

So according to this information the correct option is C.

Additional Information: Melting point of magnesium acetate $Mg{(C{H_3}COO)_2}$ is 80 degree Celsius. Magnesium acetates $Mg{(C{H_3}COO)_2}$ are white hygroscopic crystals. The hydrated magnesium chloride can be extracted from brine or sea water.
Magnesium ($Mg$ ) is a divalent cation essential for a number of biochemical processes involved in nerve signaling, bone mineralization and muscle contractions. About 350 enzymes involved in glycolysis and the Krebs cycle, formation of cyclic-AMP and ATP, cellular signal transduction and protein and nucleic acid synthesis are dependent on magnesium.

Note: Magnesium acetate $Mg{(C{H_3}COO)_2}$ is commonly used as a source of magnesium ($Mg$ ) or for the acetate ion ${(C{H_3}COO)^ - }$in chemistry experiments. The Mg2+ had a stronger tendency to bind with the acetate ion ${(C{H_3}COO)^ - }$ compared to the nitrate.
