yes
The flame of barium nitrate typically produces a pale green color when burned. This green color is a characteristic flame test color for barium compounds.
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.
first of all which are we talking? Copper (I) Nitrate or Copper (II) Nitrate 2nd, It is an Ionic Solution that will react with any metal except mercury, silver, platinum, and gold.
When a gold ring is dropped into a solution of copper nitrate, a redox reaction takes place where the gold would dissolve as gold ions, and copper from the copper nitrate would deposit onto the ring. This results in the gold ring becoming plated with a layer of copper.
Gold itself does not oxidize, but other metals mixed with the gold alloy can oxidize and cause discoloration. Italian gold jewelry, typically made with higher proportions of pure gold and less alloys, is less likely to oxidize compared to lower-quality gold alloys. Proper care and maintenance can help prevent oxidation on any type of gold jewelry.
no,it cannot
Yes, gold can oxidize and tarnish over time, but it is very resistant to corrosion compared to other metals.
One can effectively oxidize gold by using a strong oxidizing agent, such as aqua regia or chlorine gas, which can react with the gold to form gold oxide. This process is commonly used in the extraction and refining of gold.
Gold is a noble metal and is highly resistant to oxidation. It does not readily react with oxygen, water, or most acids. However, gold can potentially oxidize under extreme conditions, such as in the presence of strong oxidizing agents like aqua regia or during high-temperature processes.
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.
Although Ag (gold) is a metal, Nitrogen and Oxygen are nonmetals. Therefore, they cannot have metallic bonds.
Gold (III) nitrate has the formula Au(NO3)3.
