Unformatted text preview: nH 2 O added, where n is the number of water molecules. As usual, if n = 1 it is omitted. The formula of the hydrate is therefore: MnSO 4 7H 2 O The name of the hydrate is manganese(II) sulfate heptahydrate . The equation for the dehydration is: MnSO 4 7H 2 O MnSO 4 + 7H 2 O...
