Why is nitric acid yellow?
It is due to nitric dioxide gas contamination. Very pure nitric acid is clear because the synthesis of it removes it of nitric dioxide.
Which chemical changes the color of nitric acid?
Nitric acid in its pure form is colorless. The color changes to brownish-yellow due to the presence of nitrogen dioxide (NO2). This nitrogen dioxide usually forms when bottles containing nitric acids are not properly capped. Nitric acid reacts with oxygen in the air to form nitrogen dioxide which remains dissolved in the acid to give this particular color.
What is the purity of Nitric Acid?
Purity is a characteristic of a specific sample of a substance, rather than being a universal property of that substance. Consequently, nitric acid can be either pure or adulterated to whatever degree you may wish.
Nitric acid is used as oxidizing agent but nitrous acid used as both oxidizing agent and reducing agent why?
The pure compound is colorless, but older samples tend to acquire a yellow Nitric acid is also commonly used as a strong oxidizing agent.
Why does only dilute nitric acid react with dry sodium carbonate?
When sodium bicarbonate reacts with nitric acid, sodium nitrate salt is formed along with carbonic acid (double replacement reaction), which immediately decomposes to water and gaseous carbon dioxide (which explains the fizzing). The concentration of the nitric acid affects the rate of reaction, the more dilute it is, the slower the reaction will progress. The more pure the nitric acid, the faster the reaction will take place.

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

What is the chemical formula for mixing pure copper with nitric acid?
Cu + 4HNO3 ----> Cu(NO3)2 + 2NO2 + 2H2O
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.
Is NaNO3 a gas?
Hey! Nitric acid (HNO3), also known as aqua fortis and spirit of nitre, is a highly corrosive and toxic strong acid and it Pure anhydrous nitric acid (100%) is a colorless mobile liquid with a density of 1.522 g/cm3 I hope I helped you out!
Difference between strong acid and concentrated acid?
An acid is a substance that breaks into water to produce hydrogen ions (H+) and some other, negative ion. A strong acid is and acid that completely breaks apart into ions. (In a weak acid, only some of it breaks apart). Nitric acid is a strong acid while acetic acid is weak. A concentrated acid is one that is nearly pure. Usually 90% pure or more. So 95% nitric acid is a concentrated strong acid, while 95% acetic acid is a concentrated weak acid. Acids are usually sold dissolved in water in a low concentration. For example, vinegar is 5% acetic acid. Hydrochloric acid, another strong acid, is often sold in a 37% concentration.
How do you prepare 2N nitric acid?
It's not exactly the sort of thing you can do in your kitchen, if that's what you were hoping for. Industrially it's made by heating air to very high temperatures to roast the nitrogen into NO2, then reacting that with water to produce nitric acid.
Why toluene is burn without fume?
Toluene is burn without fume because t is made of pure carbon. Charcoal fire has no smoke because of the wood carbon.
