Give the correct formula for aluminum sulfate.<\/p>\n\n\n\n

A) Al2SO4
B) Al(SO4)3
C) Al3(SO4)2
D) Al2(SO4)3<\/p>\n\n\n\n

The correct answer and explanation is :<\/strong><\/mark><\/p>\n\n\n\n

The correct formula for aluminum sulfate is D) Al\u2082(SO\u2084)\u2083<\/strong>.<\/p>\n\n\n\n

Explanation:<\/h3>\n\n\n\n

Aluminum sulfate is an inorganic compound with the chemical formula Al\u2082(SO\u2084)\u2083. It is commonly used in water purification, as a mordant in dyeing, and in the production of paper. Understanding its formula involves recognizing the ionic nature of the compound and the charges of the constituent ions.<\/p>\n\n\n\n

    \n
  1. Aluminum Ion (Al\u00b3\u207a)<\/strong>: Aluminum, as a metal in Group 13 of the periodic table, forms a cation with a 3+ charge (Al\u00b3\u207a). This means that aluminum atoms need to lose three electrons to achieve a stable electron configuration.<\/li>\n\n\n\n
  2. Sulfate Ion (SO\u2084\u00b2\u207b)<\/strong>: The sulfate ion is a polyatomic ion consisting of one sulfur atom covalently bonded to four oxygen atoms, with an overall charge of 2- (SO\u2084\u00b2\u207b). This ion is negatively charged, meaning it needs to balance out the positive charges of the aluminum ions.<\/li>\n\n\n\n
  3. Balancing the Charges<\/strong>: To create a neutral compound, the charges must balance. Since each aluminum ion has a +3 charge and each sulfate ion has a -2 charge, the least common multiple of 3 and 2 is 6. This means that two aluminum ions (each with a +3 charge) will balance with three sulfate ions (each with a -2 charge).<\/li>\n<\/ol>\n\n\n\n

    Thus, the formula for aluminum sulfate is Al\u2082(SO\u2084)\u2083, which ensures that the total positive charge (+6) is balanced by the total negative charge (-6), resulting in a neutral compound.<\/p>\n\n\n\n

    Why the other options are incorrect:<\/h3>\n\n\n\n
      \n
    • A) Al\u2082SO\u2084<\/strong>: This does not balance the charges correctly.<\/li>\n\n\n\n
    • B) Al(SO\u2084)\u2083<\/strong>: This formula suggests one aluminum ion with three sulfate ions, which doesn’t balance the charges.<\/li>\n\n\n\n
    • C) Al\u2083(SO\u2084)\u2082<\/strong>: This also doesn’t result in a neutral charge balance.<\/li>\n<\/ul>\n\n\n\n
