Chemical equation for iron added to dilute sulfuric acid?
Iron + sulphuric acid ----> iron sulphate + hydrogen
Is dilution of sulfuric acid endothermic or exothermic?
The dilution of sulfuric acid is exothermic because it releases heat.
Why does not silver evolve hydrogen on reacting with dilute sulphuric acid?
Silver is below hydrogen in the reactivity series, so it cannot displace hydrogen from dilute sulfuric acid, which is a less reactive acid compared to hydrochloric acid. Therefore, silver does not evolve hydrogen gas when reacting with dilute sulfuric acid.
Why does copper not liberate hydrogen on reacting with dilute sulphuric acid?
it is because hydrogen gas usually liberates when an acid reacts with metal
What would happen if you put sulfuric acid in water?
When sulfuric acid is mixed with water, it will undergo an exothermic reaction that generates heat. It is important to add the acid to water slowly and carefully while stirring to prevent splashing and the release of potentially harmful fumes. This dilution process produces a solution of sulfuric acid in water.

What is left when you evaporate dilute sulfuric acid?
Driving off the water from dilute sulfuric acid will increase the concentration of the acid to the point where it will contain virtually no water.

How do you make concentrated sulfuric acid from dilute sulfuric acid?
Concentrated sulfuric acid can be made from dilute sulfuric acid by removing the water through a process such as distillation or evaporation. This can be achieved by heating the dilute sulfuric acid to bring it to its boiling point and capturing the vapors that are released, leaving behind the more concentrated sulfuric acid.
What is the ratio of water and concentrated sulfuric acid in dilute sulfuric acid?
The ratio of water to concentrated sulfuric acid in dilute sulfuric acid is typically 10:1, meaning there is about 10 times more water than concentrated sulfuric acid in the solution. This dilution is necessary to reduce the concentration of sulfuric acid for safety and handling purposes.
Why is Concentrated sulfuric acid a weaker acid compared to dilute sulfuric acid?
Concentrated sulfuric acid can act as a weaker acid compared to dilute sulfuric acid because in concentrated form, there are fewer water molecules available to donate protons, leading to fewer acidic reactions. Dilute sulfuric acid, on the other hand, has more water molecules to facilitate proton donation, making it a stronger acid.
Is dilute sulfuric acid a stronger acid compared to concentrated sulfuric acid?
No, although "concentrated" sulfuric acid (essentially pure H2SO4) is less dissociated than dilute sulfuric acid, simply because there's no water around for it to dissociate in.
Is concentrated sulfuric acid stronger than dilute sulfuric acid?
When the concentration is considered, concentrated acid contains more molecules than the dilute acid. It is only one way to measure the strength. If we consider the reactivity with the absence of water and moisture, dilute sulfuric acid is more reactive than the concentrated acid.
Why does copper not evolve hydrogen on reacting with dilute sulphuric acid?
Copper does not evolve hydrogen gas when reacting with dilute sulfuric acid because copper is below hydrogen in the reactivity series. This means that copper is not reactive enough to displace hydrogen from sulfuric acid to form hydrogen gas. Instead, copper reacts with sulfuric acid to form copper(II) sulfate and water.
