The color of mercury(II) hydroxide is tan-brown.
OH is a hydroxyl radical (as in sodium hydroxide) or the alcohol functional group.
The formula for hydrogen hydroxide is H2O.
Sodium hydroxide.
The formula for hydroxide is (OH) however, hydroxide leaves an electron un-paired and bonds with another element or elements.
The formula of mercury(I) hydroxide is Hg2(OH)2.
HgOH would be called mercury(I) hydroxide or mercurous hydroxide. This is a compound that is not well characterised, in other words it is reported by chemists but (as far as I know) the existence of the solid compound has not been proven- e.g. by x-ray crystallography. Some authors say it only exists in solution. It would contain the diatomic Hg22+ ion and the formula would be written Hg2(OH)2.
The color of mercury(II) hydroxide is tan-brown.
OH is a hydroxyl radical (as in sodium hydroxide) or the alcohol functional group.

The hydroxide ion's chemical formula is [OH]-
The formula for potassium hydroxide is KOH.
Sodium hydroxide.
The formula for hydroxide is (OH) however, hydroxide leaves an electron un-paired and bonds with another element or elements.
