How do you prepare dilute sulphuric acid from concentrated sulphuric acid?

Fill a container about half way or more with distilled water, add the acid, and then bring up to volume with more water. In the example above, fill a flask with about 150 mL or more with distilled water, add 6.9 mL of concentrated sulfuric acid, then continue to dilute with water to the 250 mL mark.)

Which of the following is not the reason for while preparing dilute sulphuric acid from concentrated sulphuric acid in the laboratory the acid is added in water *?

Answer ⇒ While Preparing Dilute Sulphuric Acid in a Laboratory, Acid is added slowly to water (Water is never added to the acid as it will be the exothermic process which can cause Fatal to the person) with constant stirring because it will not cause any harm to the Person or any Apparatus in the laboratory.

What happens when concentrated sulphuric acid is diluted?

Sulphuric acid in dilute form behaves as an acid as the protonation of water rapidly takes place and forms hydronium ions.

How concentrated sulphuric acid is diluted in the laboratory?

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…

Why is dilute sulphuric acid added while preparing a?

Explanation: sulphuric acid in the preparation of a standard solution of Mohr’s saltin redox titration is to prevent hydrolysis of the Fe2+ ions. Ferrous ions of Mohr’s salt undergo hydrolysis in aqueous solution. Another reason is also to prevent the oxidation of Fe2+ ions of Mohr’s salt to Fe3+ ions.

What is the formula of dilute sulphuric acid?

H2SO4
The formula for sulfuric acid is H2SO4. The molar mass of sulfuric acid is 98.07848 g mol.

Why is dilute sulphuric acid added while prepare?

How will you prepare dilute sulphuric acid from concentrated sulphuric acid give reason for your answer what is the effect of dilution on H+ ion concentration of the acid?

Answer: (i) Add 10 mL of concentrated sulphuric acid slowly to 90 mL of water with constant stirring. Dilution of acid is a highly exothermic process. If water is added to concentrated sulphuric acid, heat generated causes the mixture to splash leading to burns and the glass container can break.

How will you prepare dilute sulphuric acid from concentrated sulphuric acid give reason for your answer?

While preparing dilute sulphuric acid from concentrated sulphuric acid in the laboratory, the concentrated sulphuric acid is added slowly to water with constant stirring. In the process of dilution of concentrated sulphuric acid with water, very large amount of heat is liberated. This process is highly exothermic.

How is sulphuric acid prepared in the laboratory?

Manufacture. Sulfuric acid is produced from sulfur, oxygen and water via the contact process. In the first step, sulfur is burned to produce sulfur dioxide. This is then oxidised to sulfur trioxide using oxygen in the presence of a vanadium(V) oxide catalyst.

Why is dilute sulphuric acid added while preparing a standard solution of ferrous sulphate?

To prepare double salts: ferrous ammonium sulphate (Mohr’s salt) and potash alum. Fe2+ and Al3+ ions undergo hydrolysis, therefore, while preparing aqueous solutions of ferrous sulphate and aluminium sulphate in water, 2-3 mL dilute sulphuric acid is added to prevent the hydrolysis of these salts.

What happens when sulfuric acid reacts with dilute sulphuric acid?

Dilute sulfuric acid will react to produce hydrogen gas. Increasing the concentration will increase the rate of reaction. Since the product is in another phase (hydrogen is a gas) too rapid a reaction brings a risk of overpressurization and explosion.

How do you dilute sulfuric acid to 1 liter?

Notice in the case of sulfuric acid, which is dibasic, this would be a 6 normal solution. The standard recipe is to take 168 mL of concentrated sulfuric acid and dilute it to 1 liter. However, as noted in previous answers, it is important to do so in such a way that you are adding acid to water initially.

What are the properties of concentrated sulphuric acid?

Concentrated sulphuric acid is an oxidizing agent. It does not have acidic properties. It oxidizes hydrogen gas to water on reaction with metals. However, on diluting the acid, its oxidizing power is reduced and hydrogen is evolved. Where can I find information about different materials online?

Why is sulfuric acid not used for the preparation of hydrogen?

If conc. sulfuric acid is used for the preparation of hydrogen, then it’s oxidized with sulfuric acid converted into water.So,conc. sulfuric acid does not used for the preparation of hydrogen gas. Dilute sulfuric acid will react to produce hydrogen gas.
