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.
The formula for hydroxide is (OH) however, hydroxide leaves an electron un-paired and bonds with another element or elements.
Sodium hydroxide.
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 formula for hydrogen hydroxide is H2O.
The hydroxide ion's chemical formula is [OH]-
The formula for potassium hydroxide is KOH.
The formula for hydroxide is (OH) however, hydroxide leaves an electron un-paired and bonds with another element or elements.
Sodium hydroxide.
Calcium Hydroxide has a molecular formula of Ca(OH)2. The structural formula is H-O-Ca-O-H.
The chemical formula for ammonium hydroxide is NH4OH.
