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)
Why nitric acid is used in volhard method?
Nitric acid is used in the Volhard method to oxidize Fe(II) to Fe(III) in order to prevent interference in the titration of chloride ions with silver nitrate. By converting Fe(II) to Fe(III), nitric acid ensures accurate and precise results in the determination of chloride content.
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)
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.
Griess manual METHOD for nitric oxide?
The Griess assay is a simple colorimetric method used to quantify the levels of nitric oxide (NO) in a sample. In this method, nitrate and nitrite are first converted to nitrite by a nitrate reductase enzyme. The nitrite is then reacted with a Griess reagent to form a purple compound whose absorbance is measured at 540 nm. This absorbance is directly proportional to the concentration of NO in the sample.
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
Salt formed if you mix aluminium oxide and nitric acid?
The salt formed when you mix aluminum oxide and nitric acid is aluminum nitrate. Aluminum oxide reacts with nitric acid to form aluminum nitrate and water.
What happens when aluminium sulphate reacts with nitric acid?

In permanganate titration's why is nitric acid not used?
Nitric acid is not used in permanganate titrations because it can react with permanganate ions and reduce them before they can oxidize the analyte. This interference can lead to inaccurate results in the titration process. Instead, sulfuric acid is often used as the acidifying agent in permanganate titrations.
What is aluminium hydroxide plus nitric asid?
When aluminium hydroxide reacts with nitric acid, aluminum nitrate and water are formed. The balanced chemical equation for this reaction is: 2Al(OH)3 + 6HNO3 → 2Al(NO3)3 + 6H2O
Why Nitric acid can be stored in aluminium vessels?
i do not know. better refer wikipedia. sorry for the inconvenience.
What is the balanced equation of nitric acid plus aluminium oxide -aluminium nitrate plus water?
The balanced chemical equation is: 2HNO3 + Al2O3 --> 2Al(NO3)3 + 3H2O
