WebApr 1, 1987 · The wear rate of cast iron and the corrosion potential (Ecorr) and current (Icorr) were measured in sulphuric acid in order to study the mechanism of corrosive wear of cast iron. The corrosive wear rate of cast iron was found to reach a maximum at around 35 wt. percent sulphuric acid concentration and increase with load and acid temperature. … WebTreatment with sulphuric acid changes it into soluble calcium phosphate, a valuable plant food. Likewise, concentrated sulphuric acid will draw water out of the skin, leaving a dangerous burn. For a catalyst, moisten a little asbestos fiber and shake it with a quarter of its bulk of iron oxide.

WebWhen the sulfuric acid concentration was 0.64 mol L −1, some of Fe 3 O 4 decomposed to increase the iron concentration in the leachate. 30 Fig. 4 (a) The effect of the sulfuric acid concentration on the leaching rate of iron from copper tailings, (b) 1 − 2/3 X − (1 − X ) 2/3 versus time at different sulfuric acid concentrations, and (c ... WebSorted by: 1. I did some brief research and I saw that sulfuric acid can dissolve iron: Fe (s) + H 2 SO 4 (aq) → Fe 2 + (aq) + SO 4 2 − (aq) + H 2 (g) Of course, this would leave sulfate ions and perhaps some precautions would need to be taken because of hydrogen gas production. ariannaberg
