Why is dilute H2SO4 stronger than concentrated H2SO4?

Why is dilute H2SO4 stronger than concentrated H2SO4?

The presence of water in dilute sulphuric acid increases the hydrogen ion concentration. Hence it is a stronger acid than concentrated sulphuric acid which contains comparatively less water.

Is H2SO4 stronger than HSO4?

Why is HSO4–(aq) a weaker acid than H2SO4 A. Because HSO4–(aq) dissociates to a larger extent than H2SO4(aq), it is therefore a weak acid and a strong electrolyte. B. Because HSO4–(aq) only dissociates to a small extent compared to H2SO4(aq), it is therefore a weak acid and a strong electrolyte.

Which is the stronger acid H2SO4 or H2SO3?

H2SO4 is a stronger acid than H2SO3 .

What is the difference between dilute sulphuric acid and concentrated sulphuric acid?

A concentrated acid is an acid which is in either pure form or has a high concentration. Laboratory type sulfuric acid (about 98% by weight) is a concentrated (and strong) acid. A dilute acid is that in which the concentration of the water mixed in the acid is higher than the concentration of the acid itself.

Which is more reactive dilute sulphuric acid or concentrated sulphuric acid?

Dilute sulphuric acid is stronger acid as compared to concentrated sulphuric acid.

What is difference between H2SO4 and HSO4?

H2SO4 is a strong acid. When it looses a hydrogen, it becomes HSO4, and gains a negative charge. HSO4- is the conjugate base of H2SO4 but it can still give its Hydrogen away, and thus it is a weak acid as well. It’s weak because it doesn’t part with its hydrogen as easily as H2SO4 did.

Is H2SO4 strong or weak?

Strong acids are 100% ionized in solution. Weak acids are only slightly ionized. Phosphoric acid is stronger than acetic acid and so is ionized to a greater extent….Strong and Weak Acids and Acid Ionization Constant.

Acid Conjugate Base
HCl (hydrochloric acid) (strongest) Cl− (chloride ion) (weakest)
H2SO4 (sulfuric acid) HSO4− (hydrogen sulfate ion)

How do you find the density?

The Density Calculator uses the formula p=m/V, or density (p) is equal to mass (m) divided by volume (V). The calculator can use any two of the values to calculate the third. Density is defined as mass per unit volume.

What is the density of 50% H2SO4?

Density of sulfuric acid and sulfur trioxide

% (H2SO4) Density ρ at 20°C (g/cm³) mol (H2SO4)/l respectively mol (SO3)/l
48 1,3758 6,734
49 1,3854 6,921
50 1,3951 7,113
51 1,4049 7,306

Which is the stronger H2SO4?

Generally, both Hydrochloric acid (HCl) and Sulfuric acid (H2SO4) are really strong acids compared to any other acids. However, HCl is stronger than H2SO4.

Which one of the following is stronger H2SO4?

Answer and Explanation: Sulfuric acid (H2SO4 H 2 S O 4 ) is a stronger acid than sulfurous acid (H2SO3 H 2 S O 3 ). See full answer below.

Why is H2SO4 stronger than H2SeO4?

oxyacids of sulphur is more acidic then selenium because sulphur is more electronegative then selenium.Hence H2SO4 should be stronger than H2SeO4. What is the difference between H₂SO₃ and H₂SO₄? Originally Answered: What is the difference between H2SO3 and H2SO4? In H2SO3, Sulphur exhibits a valency of 4. Its oxidation number is +4.

What is the valency of sulphur in H2SO4?

In H2SO4, Sulphur exhibits a valency of 6 & its oxidation number is +6 thus making H2SO4 molecule chargeless. The major difference between H2SO3 & H2SO4 is that in H2SO3, valency of sulphur is 4 while in H2SO4, that of sulphur is 6.

Why does carbonic acid have a higher electron density than H2SO4?

Also, H 2 SO 4 has four oxygen atoms, two of which are not bonded to hydrogen atoms and therefore capable of drawing electron density away from O-H bonds. Carbonic acid, on the other hand, has only three oxygen atoms, only one of which is not bonded to hydrogen.

Is H3AsO4 a strong or weak acid?

Which acid is stronger H3AsO4 or H3AsO3? Nominally a stronger acid is one that releases free proton more readily. H3AsO4 (arsenic acid) is a much stronger acid than H3AsO3 (arsenous acid). The first pKa for arsenic acid is 2.2 while for arsenous it is 9.2. 2.2 is a moderately strong acid. 9.2 is very weak acid.
