why are iron compounds more readily oxidised by air in an alkaline medium than in an acidic medium
Iron compounds more readily oxidised by air in acidic medium,cause Fe2+ +1/2 O2 + H2O + 1ecirc; =Fe3+ 2 OH- In alkaline medium equilibrium reaction will shift toward the formation...

the ratio of numbers of mole of kmno4 and k2cr2o7 required to oxidised 0.1 mole sn2+ and sn4+ in acidic medium .
During the reaction KMnO4 and K2Cr2O7 are getting 5 and 6 electrons, respectively. At the same time Sn2+ loses 2 electrons. MnO4- + 5e + 8H+ →Mn2+ + 4H2O Cr2O72-...

How can atoms be electrically neutral when they contain charged particles?
Atom consist of three types of particles. There are proton (positive), electron (negative) and neutron particles. Atoms are neutral because the sum of the electrons is equal to the sum...
