the glucose is hydrolised by the sulfuric acid. Furfural derivates are formed. These derivates form with phenol a yellow complex wich can be measured with a spectrophotometer.

Phenol when it first reacts with conc sulfuric acid and then with conc nitric acid gives?

Phenol reacts with concentrated sulfuric acid to form the sulfonated product, and then with concentrated nitric acid to form picric acid (2,4,6-trinitrophenol).


What happens in the reaction of sodium phenoxide with sulforic acid?

In this reaction, the sodium phenoxide reacts with sulfuric acid to form phenol and sodium sulfate. The hydrogen from the sulfuric acid replaces the sodium in the phenoxide group, resulting in the formation of phenol. Sodium sulfate is formed as a byproduct.


What happens when phenol reacts with concentrated HNO3 plus H2SO4?

When phenol reacts with concentrated nitric acid (HNO3) in the presence of sulfuric acid (H2SO4), a mixture of products is formed, including picric acid (2,4,6-trinitrophenol) and water. This reaction is known as nitration of phenol and is used to synthesize picric acid, which is a yellow, explosive compound.


What happens if you put gold into sulfuric acid?

Nothing happens. Gold will not react with sulfuric acid.


What happens when glucose reacts with concentrated sulfuric acid?

The sugar is actually "dehydrated" by the acid. The result is a yucky carbon residue that is "fluffy." This means that it will expand significantly. The reason that it is so yucky is that it is wet with the (still very strong) acid.


Which is strong acid water or phenol?

A strong acid is typically stronger than phenol in terms of acidity due to its ability to fully dissociate in water to release protons. Phenol is a weak acid that only partially dissociates in water, making it less acidic compared to strong acids like hydrochloric acid or sulfuric acid.


What happens when pure gold is dropped in concentrated sulfuric acid?

Nothing happens because gold doesn't react with sulfuric acid.

What happens with the sulfuric acid and is it a chemical change or physical change?

The chemical reactions of sulfuric acid are chemical changes.


How will you convert phenol to 246 trinitrophenol?

To convert phenol to 2,4,6-trinitrophenol (picric acid), you would first nitrate phenol by treating it with a mixture of nitric and sulfuric acids. This will lead to the substitution of hydrogen atoms on the phenol ring with nitro groups, resulting in the formation of the 2,4,6-trinitrophenol compound.


Can you get phenol from carbolic acid?

Phenol and carbolic acid are actually the same compound. "Carbolic acid" is an older, colloquial term for phenol.


What is the name of H2SO4 acid?
