Why the remaining mixture of alkanes and alkenes have to discard into water for reaction with sulphuric acid?
The remaining mixture of alkanes and alkenes is discarded into water to separate the alkenes from the alkanes because alkenes are soluble in sulfuric acid and can undergo electrophilic addition reactions, while alkanes do not react with sulfuric acid. Water helps to extract the alkenes, allowing for a clearer separation of the components. Furthermore, this process minimizes the risk of unwanted reactions and ensures that only the reactive alkenes interact with sulfuric acid.
Is sulfuric acid a mixture compound or a element?
Sulfuric acid is a compound
That are the reactions in molisch tesr?
Molisch test is a qualitative chemical test used to detect the presence of carbohydrates. The reaction involves the reaction between the carbohydrate and concentrated sulfuric acid, resulting in the formation of a violet or purple color. This color change is due to the dehydration of the carbohydrate and the subsequent formation of furfural compounds.
What is Venus' color in space?
yellow and tan cuz the clouds are made of sulfuric acid
What planet has a nasty atmosphere of sulfuric acid?
Yes, although it is different from acid rain on Earth. Earth's acid rain is water with small amounts of sulfuric and nitric acid. On Venus the rain is almost entirely sulfuric acid, with no liquid water. However, this rain evaporates before it reaches the ground.

Who found alkenes?
Alkenes were first discovered by the French chemist Théophile-Jules Pelouze in 1834. He isolated the first alkene, ethylene, by heating ethanol with sulfuric acid.
What is the color of a pure sulfuric acid?
It is transparent.
What are two qualitative properties of sulfuric acid?
Sulfuric acid is a strong mineral acid that is highly corrosive and has a very high boiling point. It is also a dense, colorless liquid that is soluble in water.
What is the color of sulphuric acid?
Sulfuric acid is colorless.
Whay color is sulfuric acid?
clear
What is the color of phenoplhthalein if sulfuric acid is added?
The color is orange to red.
What is the name of H2SO4 acid?
sulfuric acid or sulphuric acid
What happens if sulfuric acid is added in phenolphthalein?
Sulfuric acid is a strong mineral acid that can react with phenolphthalein, which is a pH indicator. In the presence of sulfuric acid, phenolphthalein can turn colorless due to the acidic conditions. This color change occurs because the sulfuric acid donates protons to the phenolphthalein molecule, changing its structure and causing it to lose its pink color.
What color is car battery acid?
sulfuric acid is clear and is used in lead acid batteries for cars.
How does Propene with h2so4?
Propene can undergo electrophilic addition reaction with concentrated sulfuric acid (H2SO4) to form a sulfonic acid. The double bond in propene reacts with the sulfuric acid to form a carbocation intermediate, which then reacts with the sulfate ion of sulfuric acid to yield the final product.
Why do you not test sulfates with sulfuric acid?
Sulfate ions (SO4^2-) do not react with sulfuric acid (H2SO4) because they are already in the sulfate form and are not further oxidized or reduced by sulfuric acid. The reaction of sulfuric acid with sulfates would not result in a color change or a precipitate formation, making it impractical as a test for sulfates.
