Question

what is the chemical formula for the alum you are synthesizing, also known as potassium aluminum sulfate dodecahydrate?
select one:
baso4
kai(so4)2·12h2o
al(oh)3
kai(so4)2

Explanation:

Potassium alum (potassium aluminum sulfate dodecahydrate) is a chemical compound. Its chemical formula is \(KAl(SO_{4})_{2}\cdot12H_{2}O\). \(BaSO_{4}\) is barium sulfate. \(Al(OH)_{3}\) is aluminum hydroxide. \(KAl(SO_{4})_{2}\) is potassium aluminum sulfate (without the water of crystallization part for the dodecahydrate).

Answer:

\(KAl(SO_{4})_{2}\cdot12H_{2}O\)
