What gas is evolved when dilute nitric acid is added to Zinc?
When dilute nitric acid is added to zinc, the gas evolved is nitrogen dioxide (NO2) along with water and zinc nitrate.
What happens when dilute nitric acid and silver nitrate solution is added to sodium chloride solution What is formed when you add silver nitrate and hydrochloric acid?
When dilute nitric acid and silver nitrate solution are added to sodium chloride solution, a white precipitate of silver chloride is formed. When silver nitrate and hydrochloric acid are added, a white precipitate of silver chloride is also formed.
What dilute acid is added to a sample of limestone the rock fizzes what chemical does the rock contain?
If the limestone rock fizzes when dilute acid is added, it indicates the presence of calcium carbonate in the rock. When calcium carbonate reacts with acid, it produces carbon dioxide gas, which causes the fizzing.
Why no gas is released when sulphur is added to dilute hcl?
When sulfur is added to dilute hydrochloric acid (HCl), no gas is typically released because sulfur is a non-reactive element and does not readily react with HCl to produce a gas. Sulfur can only react with strong oxidizing agents, such as concentrated nitric acid or hot concentrated sulfuric acid, to release sulfur dioxide gas.
Why add dilute nitric acid with silver nitrate to test for halide ions?
The nitric acid reacts with other ions that might precipitate with silver nitrate. Doing this first gets these other unwanted precipitates out of the way. If you are testing with Fluoride as your halide remember that silver nitrate does not precipitate with Fluoride, so no precipitate does not mean that halide ions are not present.
What gas is evolved when dilute nitric acid is added to Zinc?
When dilute nitric acid is added to zinc, the gas evolved is nitrogen dioxide (NO2) along with water and zinc nitrate.
What happens to the atoms of copper when added dilute nitric acid is added?
(Cu)s + 2HNO3 --> Cu2+ + 2NO3- + (H2)gas
What happen to these protein when the sample is added to the wells of the microscope strip?
the proteins will go away when the sample is added
How do you dilute urine samples?
To dilute a urine sample, you can mix it with distilled water or a diluent solution in a clean container. The amount of diluent added will depend on the desired dilution ratio. Make sure to mix the sample thoroughly before testing.
What happens when dilute nitric acid and silver nitrate solution is added to sodium chloride solution What is formed when you add silver nitrate and hydrochloric acid?
When dilute nitric acid and silver nitrate solution are added to sodium chloride solution, a white precipitate of silver chloride is formed. When silver nitrate and hydrochloric acid are added, a white precipitate of silver chloride is also formed.
What observations can be made when dilute nitric acid is added to lead carbonate?
The lead carbonate is dissolved in nitric acid and carbon dioxide is released.
What will happen to the COD value if HgSO4 is not added?
Chlorine will not be seperated out of the sample effluent.

What will be the reaction if you add mercury in nitric acid on heating?
When mercury is added to nitric acid and heated, it will react to form mercury(II) nitrate along with nitric oxide gas and water. The reaction is exothermic and can be violent if not done carefully as it releases toxic nitrogen dioxide fumes.
If Clear dilute ammonia is added to blue copper sulfate solution does a chemical reaction happen?
Try it on your own. (Best answer for your problem is your action)
