Hello everybody, I need help completing the following equations and a bit more:
The hydrogen peroxide in use was 33%.
H2O2(aq) +2NaOH(s) --> Na2O2 + 2H2O.
If I'm not mistaken this should be the balanced equation, but for some reason some gas appeared when I mixed the two substances together (presumably H2O(g) because the reaction was exothermic, but I'm not sure...).
CuSO4 + H2O2(aq)---> ?
The solution acquired a dirty green color upon reaction.
2Al(s) + 6NaOH---> 2Na3AlO3(aq) + 3H2(g).
Upon dissolving aluminium (aluminium foil was used) in a ~30% solution of sodium hydroxide(might have been more or less, not quite sure) a black solution (much like oil) was formed (I assume the Na3AlO3 should be colorless).
So can anyone fix my equation or tell me what precipitants could have caused the black color in the solution?
Also, will the anion AlO3 (3-, if its an anion at all) form insoluble materials with cations like Cu (2+), Fe (3+),Mn (2+/4+) and Al (3+).
Also, how potassium permanganate (both in solid and in aquatic solution) will react with sulfuric (97%) and nitric acid (68%).
And finally, will hydrogen peroxide react with various acids (HCl,H2SO4,HNO3)?
Thanks in advance for everybody who can help answer my questions =)
