anybody can tell me what are the reaction products of the reaction
FeSO4OH + KOH
thanks

It will make more sense if you write it as [Fe(H2O)5(OH)]SO4 and if you know that iron salts are acidic. It causes the water molecule to break off as
a hydronium ion(H+). An example of one of the stages of hydrolysis is [Fe(H2O)6]<sup>3+</sup> <---->
[Fe(H2O)5(OH)]<sup>2+</sup> + H<sup>+</sup>

thanks for your reply but....

dear "guy",
thank you for your reply but I think it is not what I looked for
to explain you better i have two solids : l'hydroxide iron sulfate (FeSO4OH which is obtained by drying of solid FeSO4*H2O)
the reaction between iron sulfate monohydrate and potassium hydroxide is written:
FeSO4*H2O + 2KOH = Fe(OH)2 + K2SO4 +H2O
what im looking for is what's happen when
FeSO4OH react with KOH
the reaction is simply:
FeSO4OH+KOH=Fe(OH)2+K2SO4 or is more complicated ?

In FeSO4*H2O, iron is in +2 oxidation state. FeSO4(OH) is in the +3 oxidation state. Unless it was oxidized during drying. In that case adding more
hydroxide will cause it to hydrolyse more to form insoluble Fe(OH)3.

The reaction is that simple without air.
