What happens to glucose in the phenol sulfuric acid test?
In the phenol sulfuric acid test, glucose reacts with phenol and sulfuric acid to form a colored product. The color change is due to the formation of furfural, which reacts with the sulfuric acid to produce a colored compound. This color change is used to detect the presence of glucose in a sample.
What happens when sulphur reacts with hot and concentrated sulphuric acid?
When sulfur reacts with hot and concentrated sulfuric acid, sulfur dioxide gas is produced. This reaction is exothermic and can be quite vigorous. The sulfur dioxide gas can further react with the sulfuric acid to form additional products depending on the conditions.
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).
Does aluminum reacts with sulfuric acid?
yes... to make aluminium sulphate and hydrogen gas
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 when boron react with concentrated sulphuric acid?
When boron reacts with concentrated sulfuric acid, it forms boron trioxide (B2O3) and sulfur dioxide (SO2) as products. The reaction is characterized by the formation of a white, powdery solid of boron oxide, along with the release of heat. Additionally, concentrated sulfuric acid acts as an oxidizing agent, facilitating the oxidation of boron during the reaction.

What happens when formic acid reacts with concentrated sulphuric acid?
When formic acid reacts with concentrated sulfuric acid, a dehydration reaction occurs, resulting in the formation of carbon monoxide and water as products. This reaction is a type of dehydration reaction known as a Fischer esterification.
What happens when concentrated sulphuric acid react with hexane?
When concentrated sulfuric acid reacts with hexane, it can cause dehydration of the hexane molecule by removing a molecule of water, leading to the formation of alkenes. This reaction typically requires heat as well. Additionally, sulfuric acid is a strong acid and can also protonate hexane molecules, forming hexyl hydrogen sulfate as another possible product.
HOW Copper metal reacts with hot concentrated sulfuric acid?
Copper does not react with hot concentrated sulfuric acid due to its passivating oxide layer that prevents further reaction. The reaction between copper and sulfuric acid mainly occurs with dilute sulfuric acid, producing copper(II) sulfate and sulfur dioxide gas.
What happens when a acid and a base reacts?
It actually deepens on the acid if it's sulfuric acid then it could disintegrate
What happens when zinc reacts with concentrated sulphuric acid?
ZnSO4 FORM AND HYDROGEN GAS RELEASE.
How concentrated sulphuric acid is made from sulphur trioxide?
Concentrated sulfuric acid is made by dissolving sulfur trioxide in water. This reaction is highly exothermic, so it needs to be done with caution to prevent overheating. The resulting solution typically contains around 98% sulfuric acid.
