Magnesium carbonate is one of the compounds of magnesium generally obtained by mining magnesite. Let us learn more about Magnesium carbonate’s properties.
Magnesium carbonate is an ionic compound that is primarily used for the production of magnesium oxide. It is also used in many other things, such as flooring, fireproofing, chalk, toothpaste, etc.
In this article, we will explore Magnesium carbonate’s nomenclature, important properties, and structure.
Magnesium carbonate IUPAC name
The IUAPC name of Magnesium carbonate is magnesium carbonate.
Magnesium carbonate chemical formula
The chemical formula of Magnesium carbonate is MgCO3.
Magnesium carbonate CAS number
The CAS number of MgCO3 is 546-93-0.
Magnesium carbonate ChemSpider ID
The ChemSpider ID of Magnesium carbonate is 10563.
Magnesium carbonate chemical classification
MgCO3 is chemically classified as an inorganic salt and as a carbonate.
Magnesium carbonate molar mass
Magnesium carbonate’s Molar Mass is 26.3207. The calculation is shown below:
Magnesium carbonate color
The color of MgCO3 is white.
Magnesium carbonate viscosity
MgCO3‘s viscosity cannot be measured since it decomposes upon heating.
Magnesium carbonate molar density
The molar density of anhydrous MgCO3 is 0.0350836 mol/cm3.
Magnesium carbonate melting point
The melting point of anhydrous MgCO3 is 350 °C
Magnesium carbonate boiling point
The boiling point of MgCO3 is not known since it decomposes upon heating at high temperatures before boiling:
MgCO3 → MgO + CO2
Magnesium carbonate state at room temperature
MgCO3 is a solid at room temperature.
Magnesium carbonate ionic bond
Mg2+ and CO32- ions are joined by ionic bonds, and the bonds between C and O atoms are covalent.
Magnesium carbonate ionic radius
The radius is not defined for Magnesium carbonate since the ionic/Covalent radii are defined and measured only for atoms and not molecules. Magnesium carbonate is an ionic compound containing five atoms.
Magnesium carbonate electron configurations
Electron configurations show us how the electrons are distributed in an atomic orbital around the nucleus. Let us see the electronic configuration of MgCO3.
- The electron configuration of Mg2+ in Magnesium carbonate is 1s2 2s2 2p6, which can also be written in the noble gas configuration as [Ne]3s0.
- It is not as simple to describe the electronic configuration of CO32- by simply filling atomic orbitals since it will require complicated molecular orbitals and knowledge of symmetry and group theory.
Magnesium carbonate oxidation state
The Mg atom in Magnesium carbonate is in a +2 Oxidation state. The CO32- ion is in -2 oxidation state, where each O atom is in an oxidation state of -2, and the C atom is in a +4 oxidation state.
Magnesium carbonate alkaline
MgCO3 is alkaline and reacts with acids to form salt and carbonic acid.
MgCO3 + 2 HCl → MgCl2 + H2CO3
Is Magnesium carbonate odourless
Magnesium carbonate is odourless.
Is Magnesium carbonate paramagnetic
Paramagnetic substances are attracted to magnets; due to an unpaired electron that aligns its magnetic moment with the magnetic field. Let us see if MgCO3 is paramagnetic.
Magnesium Carbonate is not paramagnetic since all the electrons of the MgCO3 are paired in both Mg2+ and CO32- ions.
Magnesium carbonate hydrates
MgCO3 forms three different hydrates in addition to the anhydrous form:
|No. of water molecules
Magnesium carbonate crystal structure
Anhydrous magnesium carbonate, also known as Magnesite, crystallizes in a calcite structure. The hydrated forms have a triclinic structure.
Magnesium carbonate polarity and conductivity
- MgCO3 is polar since it is an ionic compound.
- MgCO3 may provide ions to conduct electricity in the molten state.
Magnesium carbonate reaction with acid
Magnesium carbonate is basic and will react with most acids to form salt and carbonic acid.
MgCO3 + H2SO4 → MgSO4 + H2CO3
Magnesium carbonate reaction with base
MgCO3 does not react with bases.
Magnesium carbonate reaction with oxide
MgCO3 is basic, so it will react with acidic oxides such as H3PO4.
3MgCO3 + 2H3PO4 → Mg3(PO4)2 + 3H2CO3
We learned about Magnesium carbonate’s physical and chemical properties, a highly versatile compound used in medicines, chalk, as an industrial precursor, and the limestone we use on our floors.
