Aluminum Sulfate Ionic or Covalent
On the bonding of aluminum sulfate
The universal thing is called aluminum sulfate, and the study of its bonding is the key to learning. To understand that it is an ionic bond or a covalent bond, it should be analyzed by reason.
Those who look at aluminum, the genus of metals, are active and prone to lose electrons. Sulfur and oxygen, non-metals, also like electrons. In aluminum sulfate, aluminum exists in an ionic state and loses electrons to form cations; in sulfate, the anion formed by sulfur and oxygen is also. Between aluminum ions and sulfate ions, electrostatic attraction is a sign of ionic bonds.
Ionic bonds, mostly between metals and non-metals, are based on the transfer of electrons. In aluminum sulfate, the interaction between aluminum and sulfate conforms to the rule of ionic bonds. When it forms a bond, the electrons of aluminum move to the sulfate group, and then form an ionic compound.
If there is a covalent bond, the atoms are bonded by a common electron pair. In aluminum sulfate, the sulfate and oxygen are connected by a covalent bond. Sulfur and oxygen have poor electronegativity, but they are not as large as ionic bonds, so they are combined by a common electron pair to stabilize their structure.
In summary, in aluminum sulfate, there are ionic bonds between aluminum ions and sulfate ions, and covalent bonds between sulfur and oxygen atoms in sulfate groups. Knowing this, the properties of aluminum sulfate and the principle of its reaction can be well understood, which is beneficial for learning and use.
