Characteristics of h2so4
What are 3 physical properties of sulfuric acid?
Physical Properties of Sulphuric Acid
- Sulfuric acid is a thick, colourless and an oily fluid.
- It has a specific gravity of 1.84 at 298 K.
- The boiling point of the acid is 611 K. …
- This strong chemical reacts with water vigorously releasing quite a lot of heat.
What makes H2SO4 a strong acid?
Sulfuric acid (H2SO4) is a strong acid. Because when it is dissolved in an aqueous solution, it completely dissociates into H+ and HSO4– ions in the solution. There is no undissociated H2SO4 present in the solution, it completely breaks off into the ions.
What is H2SO4 and its uses?
Sulphuric acid is highly acidic. Therefore, it is used in the cleaning of metals, removal of impurities from oil, manufacturing of chemicals – nitric acid, hydrochloric acid, synthesis of dye, drugs, detergents, explosives, etc.
Is H2SO4 a strong acid?
Sulfuric Acid (H2SO4, oil of vitriol) is a strong acid that is soluble in water. It is one of the most abundantly produced chemicals for industrial use including fertilizer production, ore processing, and oil refining. Sulfuric acid,HSO4, is a molecule that contains sulfur,hydrogen and oxygen.
Is H2SO4 a strong or weak base?
Sulfuric acid or H2SO4 H 2 S O 4 is a strong acid since it dissociates completely in water to form its conjugate base and hydronium ions. Its conjugate base is the hydrogen sulfate ion (HSO−4) ( H S O 4 − ) which is considered as a weak base.
Which acid is called the King of acids?
oxyacid: Sulfuric acid. Sulfuric acid is sometimes referred to as the “king of chemicals” because it is produced worldwide in… Due to its affinity for water, pure anhydrous sulfuric acid does not exist in nature.
Is H2SO4 stronger than HCl?
Acidic strength of HCl vs H2SO
Sulfuric acid and hydrochloric acids both are highly strong acids as compared to other acids but still, HCl is a stronger acid than H2SO4. This is because of the difference in the pKa value of both acids.
What is the strongest acid in the world?
fluoroantimonic acid
That title falls to fluoroantimonic acid – a superacid mixture of antimony pentafluoride and hydrofluoric acid.
What pH is H2SO4?
pH of Common Acids and Bases
| Acid | Name | 100 mM |
|---|---|---|
| H2SO4 | sulfuric acid | 1.01 |
| HI | hydroiodic acid | 1.08 |
| HBr | hydrobromic acid | 1.08 |
| HCl | hydrochloric acid | 1.08 |

Why is H2SO4 a stronger acid than HSO4?
Because HSO4–(aq) dissociates to a larger extent than H2SO4(aq), it is therefore a weak acid and a weak electrolyte. D. Because HSO4–(aq) only dissociates to a small extent compared to H2SO4(aq), it is therefore a weak acid and a weak electrolyte.
Why is sulphuric acid classified as a strong acid and Ethanoic acid classified as a weak acid?
Acetic acid ionizes partially in aqueous solution to form ions. Higher concentration of H+ ions will be the reason for strong acidic nature of sulphuric acid.
Is H2SO4 a stronger acid than HCl?
Sulfuric acid and hydrochloric acids both are highly strong acids as compared to other acids but still, HCl is a stronger acid than H2SO4. This is because of the difference in the pKa value of both acids. The pKa value of HCl is -6.3 while for H2SO4 it is -2.8.
Which one is a strong acid?
Strong Acids
| Strong Acids | Strong Bases |
|---|---|
| hydrochloric acid (HCl) | sodium hydroxide (NaOH) |
| hydrobromic acid (HBr) | potassium hydroxide (KOH) |
| hydroiodic acid (Hl) | calcium hydroxide (Ca(OH)2) |
| nitric acid (HNO3) | strontium hydroxide (Sr(OH)2) |

Is H2SO4 a weak acid?
Weak acids are only slightly ionized. Phosphoric acid is stronger than acetic acid and so is ionized to a greater extent.

What is the pH of sulfuric acid?
The pH level of sulfuric acid is 0.5, so it’s considered to be a weak acid.
Is H2SO4 a strong electrolyte?
Strong Electrolyte Examples
HCl (hydrochloric acid), H2SO4 (sulfuric acid), NaOH (sodium hydroxide) and KOH (potassium hydroxide) are all strong electrolytes.
Is H2SO4 acidic basic or neutral?
There are six common strong acids: HClO4, HI, HBr, HCl, H2SO4, and HNO3. The conjugate base of a strong acid is neutral. In contrast to strong acids, weak acids ionize only partially in aqueous solution.
Why is H2SO4 a weak base?
A 0.10 M solution of acetic acid is only about 1.3% ionized, meaning that the equilibrium strongly favors the reactants. Weak acids, like strong acids, ionize to yield the H+ ion and a conjugate base.
