What would be the color of bromothymol blue in dilute nitric acid?
Bromothymol blue would appear yellow in dilute nitric acid.
Why Should phenylalanine give a yellow Color with concentrated nitric acid?
Phenylalanine gives a yellow color with concentrated nitric acid due to the formation of a nitro derivative. Nitric acid reacts with the aromatic ring of phenylalanine, leading to the formation of a yellow compound.
Which substance turns yellow when nitric acid is dropped on it?
Potassium iodide turns yellow when nitric acid is dropped on it due to the formation of elemental iodine.
What is the action of nitric acid on Bromothymol?
Nitric acid will oxidize bromothymol blue, causing a color change from blue to yellow. This reaction is a result of the nitric acid oxidizing the alcohol groups in bromothymol to form new compounds with yellow coloration.
Why amino acids give yellow colour with nitric acid?
When amino acids react with nitric acid, a yellow color may be observed due to the formation of nitro compounds. Nitric acid can nitrate amino acids, leading to the production of yellow-colored nitro derivatives. The specific yellow color observed can vary depending on the amino acid present and the reaction conditions.

What is the colour of concentrated nitric acid?
The nitric acid used in laboratory is colorless. The very concentated nitric acid - the fumans acid - with dissolved nitrogen oxides, can release white, red or brown fumes, very corrosive and toxic.
Why bottles contain nitric acid are always yellow?
pure nitric acid is colourless and unstable and decomposes slightly even at ordinary temperatures and in the presence of sunlight. The decomposition results in formation of reddish brown nitrogen dioxide which remains dissolved in the acid thus imparting a slight yellowish brown colour.
How can you tell that gold is pure?
Provided it is yellow, put it in nitric acid. If not huing the acid, that is pure gold in contact with the acid
Colour of nitric acid in 0.1 bromothymol blue?
Nitric acid is a strong acid and will turn bromothymol blue to yellow in color because it contains protons that can react with the indicator, causing it to change color.
Why does the amino acid phenylalanine give a yellow color with concentrated nitric acid?
Phenylalanine gives a yellow color with concentrated nitric acid due to the formation of nitrophenylalanine derivatives. The concentrated nitric acid nitrates the phenylalanine, leading to the production of nitro groups that impart a yellow hue to the solution. This reaction is part of a broader class of chemical reactions involving amino acids and nitrous compounds, highlighting the interaction between amino acid side chains and strong acids.
The name of HNO3 is?
HNO3 is Nitric Acid Compare with HNO2 ; Nitrous Acid. Note the difference in the formulas and the names. Accounted for by the different oxidation states of nitrogen .
Nitric acid reacts with nitric acid?
No, it does not
