Aluminum hydroxide reaction with sulfuric acid

Bulk aluminum may undergo the following dangerous interactions exothermic reaction with butanol, methanol, 2-propanol, or other alcohols, sodium hydroxide to release explosive hydrogen gas. Reaction with diborane forms pyrophoric product. Ignition on contact with niobium oxide + sulfur. Explosive reaction with molten metal oxides, oxosalts (nitrates, sulfates), sulfides, and sodium carbonate. Reaction with arsenic trioxide + sodium arsenate + sodium hydroxide produces the toxic arsine gas. Violent reaction with chlorine trifluoride, Incandescent reaction with formic acid. Potentially violent alloy formation with palladium, platinum at mp of Al, 600°C. Vigorous dissolution reaction in... 

When WTR are sufficiently acidified with sulfuric acid (H2SO4), insoluble aluminum hydroxide in the solution is converted to aluminum sulfate, which is soluble in the aqueous medium. The stoichiometry of this reaction can be written as follows ... 

Aluminum sulfate is manufactured by the reaction of aluminum hydroxide or other aluminum raw materials, such as bauxite or kaolin, with sulfuric acid at ca. 170°C in a pressure-resistant agitator vessel. The melt obtained after concentration contains ca. 57% aluminum sulfate (ca. 13 moles of crystallization water). Double salts of aluminum sulfate with potassium, ammonium or sodium sulfate (alums e.g. potassium alum KA1(S04)2 12H2O) have been largely supplanted by aluminum sulfate. 

IRON PERSULFATE (10028-22-5) Fe2(S04)3 Light sensitive. Hygroscopic hydrolyzed slowly in water , forming acid solution and precipitates hydroxide and phosphate salts. Violent reaction with strong bases. Aqueous solution (often shipped as 73% solution) is incompatible with sulfuric acid, aluminum, caustics, alkylene oxides, ammonia, aliphatic amines, alkanolamines, amides, epichlorohydrin, organic anhydrides, isocyanates, magnesium, methyl isocyanoacetate, vinyl acetate. Corrosive to copper, copper alloys, and both mild and galvanized steel. 

EXPLOSION and FIRE CONCERNS dangerous fire and explosion hazard extremely flammable liquid NFPA rating Health 3, Flammability 3, Reactivity 1 vigorous or explosive reaction above -70°C with alkyl aluminum chlorides and aromatic hydrocarbons violently exothermic polymerization reaction with aluminum chloride, boron trifluoride, sulfuric acid incompatible or reacts strongly with nitric acid, ethylene imine, ethylenediamine, chlorsulfonic acid, oleum, sodium hydroxide combustion will produce carbon dioxide, carbon monoxide, and hydrogen chloride use carbon dioxide, alcohol foam, or dry chemical for firefighting purposes. 

When aluminum hydroxide is mixed with sulfuric acid, the products are aluminum sulfate and water. Write a balanced equation for this reaction.
