Why is aluminum wire difficult to react with dilute sulfuric acid by hydrochloric acid reaction?
And dilute sulfuric acid seems to have passivation phenomenon, will prevent further reactions
Hypothesis: Aluminum Sulfate Precipitates attached on the surface of aluminum to stop the reaction to continue the experiment design: take a bar for a period of time, immersed in dilute sulfuric acid, to see bubbles continue to build out, wash or scrape the surface of aluminum white material, aluminum strip again immersed in dilute sulfuric acid, if again bubble formation the hypothesis that.
