Which is more acidic between HNO3 or H2SO4?
Strength or acidity of an acid depends on how easily it loses its proton(s) in aqueous environment. Dissociation constant of H2SO4 (pKa=-3) is more negative than that of HNO3 (pKa=-1.38) that means H2SO4 releases protons more easily than HNO3. Therefore H2SO4 is stronger acid that HNO3.
Is nitric acid stronger than Sulphuric?
sulphuric acid is stronger than nitric acid because sulphuric acid on falling on skin forms business and turns the skin into a low Qual nitric acid is stronger oxidising agent and hence it does not cause erosion is that all sulphuric acid that is why the sulphuric acid is recognised as the king of all received sir king …
Is H2SO4 stronger acid?
Clearly, sulfuric acid has high oxidation number than sulfurous acid. So, H2SO4 central atom pulls out more electron density from the acidic proton. Hence, it is a relatively stronger acid than H2SO3. Also, H2SO4is diprotic acid that produces two H+ per molecule when dissociating in water or in an aqueous solution.
Why H2SO4 is more acidic than H2SO3?
We will rank them based on the number of oxygens and hydrogens in the oxoacid. H2SO4 has more oxygens than H2SO3, the additional oxygen will pull electrons towards itself making the O-H bond weaker. H2SO4 is a stronger acid than H2SO3 because b. it had more oxygens to weaken the H-O bond.
What is more acidic H2SO4 or H2SO3?
H2SO4 is a stronger acid than H2SO3 .
Why is H2SO4 a weak acid?
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 |
|---|---|
| H2SO4 (sulfuric acid) | HSO4− (hydrogen sulfate ion) |
| HNO3 (nitric acid) | NO3− (nitrate ion) |
| Weak Acids |
Which is a stronger acid HCl or 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. This is mainly due to the difference in the basicity of both acids. Additionally, if we look at the pKa value HCl has a pKa of -6.3 and sulfuric acid has a pKa ~-3.
