WebThe reaction of graphite with sulfuric acid in the presence of KMnO4 (oxidant : graphite ratio 0.027–0.55) involves consecutive and concurrent reactions: graphite intercalation and direct oxidation of the carbon matrix. The properties of graphite bisulfate and its reaction products are determined by the stage number of the intercalation compound; the … WebCathode reaction: Cu 2+ (aq) + 2e- → Cu(s) Anode reaction: 2H 2 O(l) → O 2 (g) + 4H + (aq) + 4e-With carbon (graphite) electrodes, the oxygen usually reacts with the anode to form CO 2. If copper is used for the electrodes, the copper anode dissolves. The reaction is the reverse of the cathode reaction.

WebWhat can react with dilute acid? Dilute acids react with relatively reactive metals such as magnesium, aluminium, zinc and iron. The products of the reaction are a salt plus hydrogen gas. Here's a good way to remember it: MASH (M+A→S+H). Does graphite react with dilute Sulphuric acid? Indeed, graphite per se, does not react with sulfuric acid ... WebOct 11, 2015 · Consider the redox reaction: $$\ce{2Fe^2+ + SO4^2- + 4H+ -> 2Fe^3+ + SO2 + 2H2O}$$ In the dilute acid, this equilibrium lies far to the left because the concentrations of $\ce{SO4^2-}$ and $\ce{H+}$ are rather low. However, making the acid more concentrated shifts the equilibrium to the right so that you get some of the products. countries with refugees fleeing
