Abstract
Mild steel undergoes reducible loss in weight during acid pickling operation in Electroplating Shop situated at SEDI-Enugu, Nigeria. The loss in weight was monitored and inhibited by acid extract of Blighia Sapida Pod .The effect of the extract was optimized by application of 23 factorial designs and optimum conditions were recorded at acid concentration of 4.41%w/v, pickling time of 1.55hrs and inhibition concentration of 5.36 g/l.The study more so revealed that increase in concentrations of the Blighia Sapida extract reduced greatly the weight losses in 0.95(%w/v) and 4.8(%w/v) concentration of hydrogen tetraoxosulphate (VI) solution respectively.
