Concentrated sulfuric acid does not dissociate completely in the aqueous solution to give ions and does not conduct electrical conductivity while dilute sulfuric acid dissociate 100% to give hydronium ions in the solution and has more acidity.
Why concentrated sulphuric acid is a weak acid?
Concentrated sulfuric acid is a weak acid (see acids and bases) and a poor electrolyte because relatively little of it is dissociated into ions at room temperature. When cold it does not react readily with such common metals as iron or copper.
Why dilute acids are stronger than concentrated acids?
Diluted acid is more stronger than concentrated because it will dissociate more . Hence more H+ ions are gained. Diluted acid is more stronger than concentrated because it will dissociate more . Hence more H+ ions are gained.
Which is more acidic dilute sulphuric acid or concentrated sulphuric acid?
Due to the presence hgher amount of water in dilute sulphuric acid, it has a higher concentration of hydronium ions than concentrated sulphuric acid. Hence it is more acidic.
Why dilute sulphuric acid is more corrosive than concentrated?
H2SO4 itself is oxidizing agent] to the metal surface through the corrosion product layer (FeSO4) destabilizes the protective FeSO4 layer. Corrosion rate increases with the loss of stability of the FeSO4 layer.
Is dilute sulphuric acid a strong or weak acid?
Dilute sulphuric acid is a strong acid and it completely ionizes in water giving hydrogen ions and sulfate ions and maintains the high acidity of the solution.
Which acid is stronger dilute acid or concentrated acid?
Concentrate acids are stronger acids that dilute acids. Concentrated acids contain very little water.
What is the difference between weak and dilute acids?
The key difference between weak acid and dilute acid is that weak acid is a compound that partially dissociates when dissolved in water, whereas dilute acid is a solution containing more water than acid. Therefore, acids have a pH lower than 7.
What is the difference between dilute acid and concentrated acid?
A concentrated acid is one in which many acid molecules are dissolved in a set volume of solution, while a dilute acid will have very few molecules per unit volume. The same applies for bases as acids. By adding water to a concentrated acid or base, the solution is diluted.
Which is more reactive concentrated or dilute?
Dilute sulphuric acid is stronger acid as compared to concentrated sulphuric acid.
Is concentrated H2SO4 a strong acid?
Sulfuric acid is a very strong acid; in aqueous solutions it ionizes completely to form hydronium ions (H3O+) and hydrogen sulfate ions (HSO4−).
Why dilute acid is more corrosive?
A concentrated acid has a higher concentration of H3O+ ions per unit volume as compared to its diluted counterpart. Thus, the natural answer is that concentrated HCl is more corrosive as compared to diluted HCl. More corrosive is obviously concentrated one .
Are concentrated acids more corrosive than dilute acids?
Concentrated acids
They are much more dangerous than dilute acids. Concentrated acids are corrosive . They can attack metals and destroy skin if spilled.
Is dilute sulphuric acid corrosive?
Diluted sulfuric acid is more corrosive than concentrated sulfuric acid (70-99%).
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.
Which is the weakest acid?
Hydrofluoric acid is the only weak acid produced by a reaction between hydrogen and halogen (HF).
What is the difference between dilute and concentrated?
The main difference between the dilute solution and concentrated solution is that dilute solution contains less solute and the concentrated solution contains more solute. A liquid with a high solute concentration is called a concentrated solution.
What is difference between strong acid and weak acid?
Any acid that dissociates 100% into ions is called a strong acid. If it does not dissociate 100%, it is a weak acid.
Why are dilute acids strong?
Dilute acids produce a large number of hydronium ions so they behave like strong electrolytes.
Why use concentrated HCl instead of dilute?
Stock (concentrated) HCl is already diluted in water, around 30% HCl. Diluting this also helps keep HCl vapor from forming, which is a serious health hazard. In reactions, it produces a H+ ion which allows for many reactions to occur.
Why is a dilute strong acid not the same as a weak acid?
No they are not the same because a weak acid is an acid which is weak in its nature.Eg acetic acid present in vinegar that we use in homes whereas a dilute acid means a concentrated acid or a strong acid that has been made weak by adding water to it.
