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.

Concentrated sulfuric acid has sulfuric acid molecules where dilute sulfuric acid has sulfate ions and hydrogen ions. Water in the diluted solution acts as the ionization medium.

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.

It depends on how diluted the dilute sulphuric acid is (i.e. its concentration).

Concentrated sulfuric acid might, but dilute sulfuric acid does not corrode copper.

The most fizzing will come from the concentrated sulfuric acid, then dilute sulfuric acid, then the acetic acid.The amount of fizzing is due to the concentration of H+ in the solution, and concentrated sulfuric acid has the most H+ in solution. The dilute sulfuric acid has less (because it is dilute) and the acetic acid solution has the least of all because it is a weak acid rather than a strong acid.See the Related Questions for more information.

Because concentrated solution has more acidic particles as compared to dilute acid, so when there is no reaction with dilute acid then we use the concentrated acid.

Dilute solutions of sulfuric acid conducts electricity because there are free ions, although concentrated sulfuric acid don't.

Yes, water and concentrated sulfuric acid can be mixed together to form dilute sulfuric acid solution.

A solution that contains a large amount of solute when compared to the volume of the solvent is called a concentrated solution. Examples of concentrated solutions are hydrochloric acid and sulfuric acid. A dilute solution is one where the amount of solute is small compared to the solvent.

I would like to dilute some 5N sulfuric acid with water, and make 0.1N sulfuric acid solution. I want 1000ml of 0.1N . I think it's a 50 to 1 ration, but just want to make sure. <Volume of concentrated> x <Concentration of Concentrated> = <Volume of dilute> x <Concentration of dilute> Therefore, <Volume of concentrated> = <Volume of dilute> x <Concentration of dilute> / <Concentration of dilute> = 1000 mL x 0.1 N / 5N = 20 mL. Meaning: Dilute 20 mL of the 5N H2SO4 to 1000 mL in a volumetetric flask will give you 1000 mLs of 0.1 N H2SO4 (aq.).

the acid to water slowly while stirring constantly

the difference between concentrated and dilute is concentrated is larger while dilute is smaller. can have concentrated solutions, or dilute solutions, but I can't imagine a concentrated dilute solution unless the solution you diluted was REALLY concentrated.

You get dilute sulphuric acid. A point to note though, concentrated acids are dehydrating agents.

Dilute sulfuric acid has no effect on sugar. However, if the acid is sufficiently concentrated, the sugar decomposes to form carbon soot, which is black in color.

Compare and contrast the properties of dilute and concentrated solutions is because you can dilute you solvent into a solution and then you have a concentrated solution.

no reaction will take place because copper does not react with dilute sulphuric acid, it will only react with hot and concentrated sulphuric acid.

Sulphuric acid should be diluted by adding acid to water while stirring continuously.

Concentrated Is a full focus. And Dilute is a total opposite acid. as concentrated is in your body, and dilure is in your foods.

If it is added to a solution of dilute sulfuric acid, it will react slowly liberating hydrogen gas. With concentrated acid, iron will undergo a series of red-ox reactions.

This statement is true regarding to surroundings without any water and moisture. In the dilute acid solutions, the sulfuric acid molecules are been ionized into hydrogen ions and sulfate ions. The 'free' protons can easily combine with any other substance. Whereas, concentrated sulfuric acid is not ionized it is not possible to release protons.

It will react with a dilute sulfuric acid solution. It will also react with pure water though.
