The Role of Sulphuric Acid in Copper Plating

Dec 11,2009·2004.A.The sulfuric acid in a copper electrolyte is there for two reasons,one is to keep the copper in solution,you only used a 0,1 m solution,if you use higher concentrations your copper sulfate will partially get Cu(OH) 2.Also the sulfuric acid gives you a better conductivity and with this comes a better throwing power.Use of Stainless Steel for Concentrated Sulfuric Acid (98%)For 98% H2SO4,Cast Iron works well (esp.for pumping of acid),whereas CS and SS do not.Use of mechanical seals with Alloy-20 sleeve and gland plate is recommended.However if the concentration of the acid falls even by 2-3%,corrosion sets in.Of course,Alloy 20 is the correct choice,if the cost of equipment is not a constraint.Sudhir Kulkarnicontact process Reaction,Conditions,Types, Facts Contact process,modern industrial method of producing sulfuric acid; it has largely replaced the chamber,or lead-chamber,process.Sulfur dioxide and oxygen,passed over a hot catalyst,unite to form sulfur dioxide,which in turn combines with water to make sulfuric acid.

sulfuric acid Uses of Sulfuric Acid Infoplease

Sulfuric acid is used in processing metals,e.g.,in pickling (cleaning) iron and steel before plating them with tin or zinc.Rayon is made with sulfuric acid.It serves as the electrolyte in the lead-acid storage battery commonly used in motor vehicles (acid for this use,containing about 33% H 2 SO 4 and with specific gravity about 1.25,is often called battery acid).
