Formula For Aluminum Sulfate
Nowadays, there is a formula for alum and aluminum, and it is necessary to clarify its theory. Alum and aluminum are the qualities of aluminum combined with sulfur and oxygen. To obtain the formula, first know the valence state of each element. The valence state of aluminum is usually positive trivalent, sulfur in sulfate is positive hexavalent, and oxygen is negative divalent.
Sulfate is composed of monosulfur and tetraoxygen, and its valence state is negative two. In order for the compound to be electrically neutral, aluminum ions and sulfate ions need to be combined in an appropriate ratio. According to the principle of the valence algebra sum of zero, the combination of dialuminum ion (positive trivalent multiplied by two to get positive hexavalent) and trisulfate ion (negative divalent multiplied by three to get negative hexavalent) can obtain the formula of alum aluminum as $Al_2 (SO_4) _3 $. This formula accurately reflects the number of atoms of each element in alum aluminum, which is of crucial significance in chemistry, such as reaction resolution and quantity calculation.
