What is the color of the flame of barium nitrate?
Yellow-Green
What do you use gold chloride for?
Gold chloride, also known as auric chloride (AuCl3), serves as a mild acid catalyst for other reactions of potential value in the preparation of pharmaceuticals.
Ionic formula for gold sulfate?
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].
How do you write the formula for gold three sulfate?
Gold (III) Sulfate is an extremely unstable compound with the molecular formula Au2(SO4)3 and ionic formula Au3+2 (SO4)2-3.
What is the name of this compound Au2S3?
The best name is gold(I) sulfide, as the oxidation state is +1. Another good name is digold sulfide which gives the stoichiometry. Some people use aurous and auric for oxidation s states 1 and 3- so they'd call this aurous sulfide. Gold has a lot of oxidation states - +1,+2,+3 and +5, aurous/auric dates from a time when only +1 and +3 were known.
How can chemical properties be used to separate substances in a mixture or a compound?
Examples:- gold can be separated from powdered rocks and sands because gold can form an amalgam with Mercury- barium can be separated from a solution adding a sulfate; the barium sulfate is formed as an insoluble precipitate in water. The separation is easy by filtration.- water can be extracted from ethanol with calcium chloride or molecular sievesby its properties which you can search sm more on the net
What happens when gold is put in copper sulfate?
Any reaction occur when gold is put in copper sulfate.
One gold sulfate molecule reacts with three hydrogen molecule to make hydrogen sulfate and gold A gold sulfate molecule includes two gold atoms How many gold atoms will be present after this reaction?
hydrogen is not a molecule.
What happens when sodium chloride is mixed with gold?
You get a mixture of sodium chloride and gold. There will be no chemical reaction. Gold is very unreactive.
What is the reaction of Gold with copper sulfate?
At STP, there will be no reaction. Gold is much less active than copper so there will be negligible gold sulfate formed by substitution. Gold is the lowest metal in the electrochemical series, so it will not react chemically with salts of any other metal.
Will gold react with hydrogen sulfate?
There are two sulphides of gold - Gold(I) sulfide (Au2S) and gold(III) sulfide, (Au2S3). Gold sulphides can be prepared treating gold chloride with hydrogen sulfide or by treating dicyanoaurate: in the reaction H2S + 2 KAu(CN)2 → Au2S + 2 KCN + 2 HCN
What is AuCl3 named?
Gold(III) chloride

This is a question from a test on NovaNET copyrighted by Pearson Publishing company. Whoever posted this question, should not have. The answer, however, has nothing to do with chemical reactions, which is taught in lessons later than this test. The answer refers to conservation of matter, and is buried in the question itself.
How do separate gold from sodium gold chloride?
You can separate gold from sodium gold chloride by adding zinc powder to the sodium gold chloride and heating the mixture. Then you will be left with just gold.
What is the chemical formula for gold (III) chloride?
Most commonly it is AuCl3 for gold(III) chloride. Gold(I) chloride would be AuCl.
What is the chemical formula for gold chloride?
Gold and silver are elements. The symbol for gold is Au, and the symbol for silver is Ag.
