Manganese (II) chloride and sodium hydroxide

  1. May 9, 2010 #1
    I reacted a solution of manganese (II) chloride with sodium hydroxide, however I am unsure of the reaction.
    Do the hydroxide ions displace the chloride ions or take a hydrogen from the water in the complex? Also after that reaction i added a few drops of hyrdogen peroxide, which caused a vigorous reaction and the colour to darken to a dark brown. Is the hydrogen peroxide oxidising the manganese? How do I write this as an equation?
    Thanks

    Please elaborate what you mean, while first idea is clear, the second one is not.

    Yes.

    First step will be to find out what is the brown product. Googling for "brown manganese" should give you some ideas.

    Are you sure chlorides are ligands?
