What gives when sodium chloride on treating concentrated sulphuric acid?
Any reaction occur.
What happens when sulphur reacts with hot and concentrated sulphuric acid?
maybe no reaction takes place;)
What did you observe when concentrated sulphuric acid was added to the reaction mixture?
I think it makes the equation to be more balanced
What is the reaction when sodium bicarbonate and concentrated sulphuric acid are mixed?
The reaction is 2NaHCO3 + H2SO4--> Na2SO4 + 2CO2 + 2H2O. The products are sodium sulfate, carbon dioxide, and water.
What occurs when copper reacts with dilute sulphuric acid?
no reaction will take place because copper does not react with dilute sulphuric acid, it will only react with hot and concentrated sulphuric acid.
What are the products formed from a reaction between hydrogen idiode and sulfuric acid?
There will be no reaction between Hydrogen Iodide and sulphuric acid. If the acid are is dilute a soution of both will be formed, if the acid is concentrated these compounds are immiscible. hydrogen iodide and sulphuric acid are actually a product of a reaction (known as the Bunsen reaction) 2H2O + SO2 + I2 → H2SO4 + 2HI
Do acids react vigorously with metals?
Yes, best example, copper and hot concentrated sulphuric acid, that is a real nasty vigorous reaction! :D
Is it dangerous adding water to concentrated sulphuric acid?
yes it is dangerous, becasue it will become warmer and then a exothermic reaction will happen hope this helped ;D
What happens when you mix water and sulphuric acid?
when we add water n sulphuric acid then dilute sulphuric acid is formed. But we have to mix concentrated acid to water not water to acid otherwise the container in which u r mixing may explode because this reaction is highly exothermic.
How does copper reacts with acid when copper is below hydrogen in reactivity series?
Cu does not reacts with dilute sulphuric acid but concentrated sulphuric acid reacts with copper inpresence of oxygen and heat here last two factors are responsible for the reaction of copper.
What happens when benzene is treated with a mixture of concentrated sulphuric acid and nitric acid?
That's an electrophilic aromatic substitution reaction ad will replace a hydrogen with a NO2 group on the ring
Why ammonia cannot be dried up using concentrated sulfuric acid?
Ammonia is basic and Sulphuric acid is acidic. hence it undergo acid base reaction forming salt and water
