The valency or valency chart is helpful in order to determine how many atoms of an element will combine with another element to form any chemical formula. Another important use of valency of elements is to find or deduce formulae of compounds. If we know the valency of elements, then we can easily write formulae of compounds of those elements.
Formula of Aluminum sulphate : Option (D) Al2 ( SO4) 3 Is the correct option. Valency of Aluminium = +3 . And formula of sulphate =( SO 4 ) Valency of sulphate = +2 . On combining / cross multiplying, It becomes Al2( SO4) 3. ♥️QED
