What is the colour of Hexaaquamanganese(II)
pale pink, but when dilute will most likely appear colourless
what is the colour of tetraaquadihydroxomanganese(ii) complex
a white precipitate that might not be seen as the precipitate rapidly turns pale brown so the final result will be pale brown
what are the reaction, reaction type, and colour change with aq NaOH is added to a solution containing

what happens to the pale brown colour o tetraaquadihydroxomanganese(ii) complex when left in air
it will turn dark brown as it is oxidized to form [Mn(H2O)3(OH)3]^-, then it will turn very dark brown forming hydrated manganese(IV) oxide MnO2.xH2O
tetraaquadihydroxomanganese(ii) doesnt dissolve in
excess NaOH
what is the reaction, reaction type, colour change when aq ammonia is added to hexaaquamanganese(ii) complex
page 207
why is the end colour of the reactions between Hexaaquamanganese(ii) and NH3 AND NaOH (both aq) a brown precipitate and nit white
even though the tetraaquadihydroxomanganese(ii) complex is white it will rapidly change to brown so like slay
