Griess manual METHOD for nitric oxide?
if the deproteinazation is important for estimation nitric oxide
What happens when aluminium reacts with nitric acid?
Aluminium reacts with dilute nitric acid to give aluminium nitrate and hydrogen gas. aluminium + nitric acid -> aluminium nitrate + hydrogen 2Al(s) + 6HNO3 (aq) -> 2Al(NO3)3 (aq) + 3H2(g)
What happens when aluminium reacts with dilute nitric acid?
Aluminium reacts with dilute nitric acid to give aluminium nitrate and hydrogen gas. aluminium + nitric acid -> aluminium nitrate + hydrogen 2Al(s) + 6HNO3 (aq) -> 2Al(NO3)3 (aq) + 3H2(g)
In permanganate titration's why is nitric acid not used?
Nitric acid, being a strong oxidising agent, interferes with oxidising capacity of KMnO4 hence reducing accuracy of titration.
Salt formed if you mix aluminium oxide and nitric acid?
This salt is aluminium nitrate.
Why aluminium is passive toward concentrated nitric acid?
Because when aluminium comes into contact with nitric acid, an impervious layer ofaluminium oxide is formed. This layer of aluminium oxide will prevent the nitric acid from coming into contact with the inner aluminium metal. Thus this layer protect and prevent further reaction.
Why nitric acid is used in volhard method?
The titration must be done in acidic medium to prevent the precipitate of Iron(III) as hydrated oxide (iron hydroxide). Iron (III) is an indicator.
What help to determine whether it silver or aluminum?
Pouring concentrated Nitric acid(HNO3). It will dissolve Silver but not Aluminium because, Aluminium will form a passivation layer which is resistant to Nitric acid
Why you can store nitric acid in aluminium container?
Nitric acid is a strong reducing agent , aluminum forms a thick layer of oxide on it while reacting with air and further nitric acid cannot oxidise Al oxide ans so nitric acid can be stored safely in it.
Why does the action of concentrated nitric acid render aluminum passive?
nitric acid is light sensitve , it decomposes when expose in light. when aluminium is added to the conc HNO3 it remain passive in conc nitric acid,...... and moreover aluminium oxide layer is also form due to which it remain passive in conc nitric acid...
What happens when aluminium sulphate reacts with nitric acid?
Answer plc urgent
What you can mix in nitric acid?
Nitric acid is very corrosive and a very strong acid. You can mix in water but remember add acid to the water and not water to the acid. When mixed with concentrated sulfuric acid it forms an excellent nitrating mixture for organic compounds. When doing a chloride titration with Silver Nitrate, Nitric acid is used to acidify and help the titration. There are many other uses also which involve mixing chemicals with nitric acid.
