Can the reaction of copper with concentrated sulfuric acid be written as an ion equation
No. Not all ionic reactions can write ion equations. Secondary schools mainly write ion equations of "electrolyte in aqueous solution" reaction. Concentrated sulfuric acid is not aqueous solution, so the reaction between concentrated sulfuric acid and solid matter can not write ion equations. Secondary schools also occasionally write ion equations of electrolyte in molten state, such as:2Al2O3...
An ionic equation for the reaction of copper with concentrated sulfuric acid. Cu+2H2SO4=heating=CuSO4+SO2 2H2O The teacher said: There is no ion equation. Q: Why there is no ion equation,[ SO4 2-] Can't you cancel it? An ionic equation for the reaction of copper with concentrated sulfuric acid. Cu+2H2SO4= heating = CuSO4+SO2 2H2O The teacher said: There is no ion equation. Q: Why there is no ion equation,[ SO4 2-] Can't you cancel?
Usually, only the reaction in water is used to write the ion equation. However, the concentrated H2SO4 is mostly in the form of H2SO4 molecule in the solution, and the ions are seldom ionized. Therefore, the ion equation is not written.
