What happens when you add concentrated sulfuric acid to water?

Sulfuric acid (H2SO4) reacts very vigorously with water in a highly exothermic reaction. If you add water to concentrated sulfuric acid, it can boil and spit and you may get a nasty acid burn.

How does Sulphuric acid act as a dehydrating agent?

Sulphuric acid removes water from substances and for drying gases, it acts as a drying agent. It also removes chemically combined water from compounds due to its strong affinity towards water and acts as a dehydrating agent.

Can concentrated Sulphuric acid be used as a drying agent?

Concentrated sulfuric acid has a very strong affinity for water. It is sometimes used as a drying agent and can be used to dehydrate (chemically remove water from) many compounds, e.g., carbohydrates.

How can concentrated sulphuric acid be diluted describe the process?

Yes it can be made diluted by adding water. so dilution of the acid is done by adding the acid into water so that all the heat produced is absorbed by water… so dilution of the acid is done by adding the acid into water so that all the heat produced is absorbed by water…

What happens when water is added to concentrated acid?

Heat is released when strong acids are mixed with water. If you add water to acid, you form an extremely concentrated solution of acid initially and the solution may boil very violently, splashing concentrated acid.

Why do we add sulphuric acid during electrolysis of water?

Because adding dilute sulphuric acid makes it slightly acidic, that mesns the water gets impure and thus electricity flows through it easily. In other words, adding sulphuric acid makes water more conductive thus making current flow through it.

Why concentrated sulphuric acid is used as drying agent and dehydrating agent?

Concentrated Sulphuric Acid is used as a drying and Dehydrating agent because it has a strong affinity for water and thus it absorbs water quickly.

Why does sulphuric acid always acts as an oxidizing agent?

Since ${H_2}S{O_4}$ is a strong acid, it reacts with a weak amphoteric base water in dilute concentrations to produce ${H_3}O$ + ions. As a result, concentrated sulfuric acid produces nascent oxygen and ${H_2}S{O_3}$. This nascent oxygen serves as an oxidizer.

What is the purpose of the concentrated sulfuric acid used in the experiment?

A small amount of a strong acid is used as a catalyst which speeds up the reaction. In this experiment, sulfuric acid will be used as the catalyst. The excess acetic anhydride will be quenched (reacted) with the addition of water.

What happens when you add sulfuric acid to water?

Concentrated sulfuric acid has a strong affinity for water and will react violent and generate heat when coming into contact with water. Always add acid to the water when diluting sulfuric acid. A large amount of heat may be released, and could cause burns.

How do you avoid a violent reaction with sulfuric acid?

Avoid a violent reaction by adding water as slowly as possible to a small amount of sulfuric acid. Since concentrated sulfuric acid of about 8M is denser than water, the water will float on the surface and the reaction begins there.

What are the characteristics of sulfuric acid?

IDENTIFICATION: Sulfuric acid is a dense, oily liquid that can be colorless to brown, depending on the purity. It can also exist as ice- or fiber-like crystals or as a gas. Sulfuric acid is also called battery acid. It is odorless with a strong acid taste. Sulfuric acid reacts violently with water, generating much heat. It is highly corrosive.

How do you dilute sulfuric acid in a process stream?

Sulfuric acid typically requires additional diffusion or mixing techniques to assure reliable diffusion into the process stream without damage to the process piping. If at all possible, it is best to predilute the acid down to 0.5\%-3\% concentration. (Acid dilution is discussed at the bottom of this page).
