Manganese (II) chloride and sodium hydroxide

TheTourist

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.

The manganese is in a complex [Mn(H₂O)₄Cl₂]
Do the -OH ions react with the chloride ions in the complex or displace with a hydrogen in the water molecules in the complex to form a new water molecule and leave a -OH ligand in the complex?

Are you sure chlorides are ligands?
