Mercury (I) Hydroxide Hg OH2 (2 is subscript) Mercury(II) Hydroxide Hg (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.
Ag+1 OH-1
LiOH born from Li+1 (Lithium) and OH-1 (Hydroxide)
The color of mercury(II) hydroxide is tan-brown.
The chemical formula for mercury 1 carbide is Hg2C.
Ag+1 OH-1 ----> these are the ions and their charges AgOH ---> the charges have to add up to zero, so one +1 Ag ion cancels out one -1 hydroxide ion AgOH ---> final formula
The formula for the ionic compound formed from potassium hydroxide is KOH. This is because potassium (K) has a +1 charge and hydroxide (OH) has a -1 charge, so they combine in a 1:1 ratio to form a neutral compound.
Mg has an oxidation state of +2 & hydroxide has the oxidation state of -1. Formula of Magnesium hydroxide is Mg(OH)2
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]-
