Gold (III) nitrate has the formula Au(NO3)3.
The ionic formula for gold(II) nitrate is Au(NO3)2.
The ionic formula for gold chloride is AuCl3. This indicates that one gold ion (Au3+) combines with three chloride ions (Cl-) to form the compound gold chloride.
The formula for gold bromide is AuBr3. Gold bromide is an ionic compound composed of one gold ion (Au3+) and three bromide ions (Br-).
The molecular formula for gold nitrate is Au(NO3)3.
The systematic name of this compound is Gold(III) Phosphate.
The ionic formula for gold(II) nitrate is Au(NO3)2.
The ionic formula for gold chloride is AuCl3. This indicates that one gold ion (Au3+) combines with three chloride ions (Cl-) to form the compound gold chloride.
The formula for gold is Au and the formula for fluoride is F-. When they combine, they form the ionic compound gold(III) fluoride, which has the formula AuF3.
The formula for gold bromide is AuBr3. Gold bromide is an ionic compound composed of one gold ion (Au3+) and three bromide ions (Br-).
The molecular formula for gold nitrate is Au(NO3)3.
The simplest Gold Sulfate compound is Gold (II) Sulfate AuSO4, ionic formula Au2+ SO42-. There also exists a very unstable Gold (III) Sulfate Au2(SO4)3, ionic formula Au3+2 (SO4)2-3. Additionally, gold forms a number of quite complex sulfate structures such as (a) the Gold (III) Sulfate ion[Au(S04)2]1-, ionic formula [Au3+ (SO4)2-2]1- (b) the Auryl Sulfate compound AuOHSO4, ionic formula Au3+ (OH)1- (SO4)2- (c) the infinite sheet stack described by the formula [(Au2)(SO4)4/2], ionic formula [(Au4+2) (SO4)2-4/2].
The nitrate anion is a large, monovalent moiety. Gold is also a fairly large cation, so, although the charge is +1, the effective attraction over that distance is somewhat lessened. These two factors make it easy for a polar solvent (like water) to separate gold nitrate into its respective ionic species. For the record, I cannot think of a single non-soluble nitrate compound.
The systematic name of this compound is Gold(III) Phosphate.
Formula: Au(NO3)3
When iron is added to gold nitrate solution, no reaction occurs because iron is not reactive enough to displace gold from its nitrate compound. Gold nitrate would remain unchanged.
Auric nitrate, now more commonly known as gold (III) nitrate, has the formula Au(NO3)3.
Gold is a metal and so its bonding is via 'Sea of Electrons'. This is not perfectly ionic nor perfectly covalent. Rather, the valence electrons are delocalised and moving within atomic orbitals of all immediate neighbouring atoms...
