Is this a radix reaction? Explain what mass of rust can be removed by the 500 mL of 0.15 M solution of oxalic acid? Rust stains can be removed by washing a surface with a dilute solution of oxalic acid (H2 C2 O4). The reaction is:
Fe2 O3 (s) + H2 C2O4 (aq) yieldsFe(C2 O4)33- (aq) + H2 O (l) +H+ (aq)
