    What does Oxidizable matter oxygen mean?

    BS EN ISO 3696, in page 10 a table, shows the requirements for different grades of water. This table mentions a term, Oxidizable matter oxygen. I know what BOD (biological oxygen demand) and COD (chemical oxygen demand) are, but I don't have clear idea about oxidizable matter oxygen. I am...

    Are my oxidation, reduction and balanced equation correct?

    I just want to know if the following makes any sense. If it doesn, what am I doing wrong? Oxidation: Mg(s) → Mg2+(aq) +*2e Reduction: Cu2+(aq) + 2e → Cu(s) Balanced equation: 2 Cu3+(aq) + Mg(s) → 2 Cu(s) + 2 Mg2+(aq) Thanks guys in advance!

    Silane oxidation mechanism

    Hi, I am trying to work out the mechanism for the formation of diphenylsilanediol (Ph2Si(OH)2) from diphenylsilane (Ph2SiH2). The other reagents used in addition to the diphenylsilane are sodium tert-butoxide and acetonitrile and the reaction is catalysed by gold nanoparticles. I believe...

    oxidation?

    I am by no means a chemist but I am curious about oxidation on copper what causes it and is it a process that can be reversed while returning the metal to its original color before oxidation?

    Oxidizing agents in natural waters

    I have the following question to complete for an assignment: Iron (III) hydroxide can act as an oxidizing agent as indicated by the half reaction Fe(OH)3 +3H3O+ + e-Fe+2 +6H2O Eo = 1.005 V (a) Assuming pH7, can the oxidation of NH4+ to NO3- be affected by this reaction in the natural waters...

    oxidation number quick help

    Im finding oxidation numbers and am in a jam. N2O2 - find the oxidation number of N I worked it out giving a -4 for oxygen (-2 valence x 2 oxygen present) Then i needed something times 2 to balance the reaction to 0, and N only has -3 or +5 how could that work? The same goes for C4H10O, and...

    Oxidation number of water

    ok so i am trying to figure out this ion-electron method and so far no one has been able to help me figure out why in the equation K + H2O ----> KOH + H2 why does water have an oxidation number of 1? Shouldn't it be zero? thanks!
