For example, alum (potassium aluminum sulfate) is kal(so4)2·12h2o, Mohr's salt (ferrous ammonium sulfate) is (nh4)2fe(so4)2·6h2o, and iron alum (potassium iron sulfate) is kfe(so4)2·12h2o. Double salt dissolves in water. The chemical formula of alum is kal(so4)2·12h2o. Alum can also be used to prepare aluminum salts, baking powder, paints, tanning materials, clarifiers, mordants, papermaking, waterproofing agents, etc. At 20 degrees and 1 standard atmosphere, the solubility of alum in water is approximately 5.90g. Courage. (1) kal: calorie (abbreviation, caloric); (2) kcal: kilocalorie (kilocalorie); (3) j: joule (abbreviation, joule); (4) kj: kilojoule. Unit conversion (1) 1 kilocalorie (kcal) = 4.184 kilojoules (kj); (2) 1 kilojoule (kj) = 0.239.

Please write the equation for the reaction between alum solution and ba (oh)2 solution. The ratio of barium hydroxide to alum is different. The precipitates generated during the reaction are also different. Less than or equal to 1:2. When reacting, only baso4 precipitates: kal (so4)2+2ba (oh)2=2baso4 (sink.
