If a sufficient amount of zinc reacts with 100 mol of concentrated sulfuric acid, what is the amount of sulfuric acid to be reduced?
Before considering the specific amount, consider two equations: Zn+2H2SO4(concentrated)=ZnSO4+SO2+2H2OZn+H2SO4=ZnSO4+H2O4(gas) Concentrated zinc oxide produces water at the same time, the concentration decreases, when it becomes dilute sulfuric acid, only simple replacement occurs, no redox reaction. Now we only need to know at what concentration...
Before the specific amount is involved, two equations are considered: Zn+2H2SO4(concentrated)=ZnSO4+SO2+2H2OZn+H2SO4=ZnSO4+H2O2(gaseous) concentrated sulfuric acid zinc oxide produces water at the same time, the concentration decreases, when it becomes dilute sulfuric acid, only a simple replacement occurs, and there is no redox reaction. Now it is only necessary to know the concentration.
Given solution density: concentrated sulfuric acid > concentrated nitric acid, if concentrated sulfuric acid is mixed with concentrated nitric acid, how to operate?
In the fume hood, pour the concentrated sulfuric acid into the concentrated nitric acid along the cup wall and stir it continuously
In the fume hood, the concentrated sulfuric acid is injected into the concentrated nitric acid along the cup wall and is constantly stirred
