Why Sulphuric acid is stronger acid than nitric acid?
H2SO4 dissociates to 2H(+) + SO4(2-) while HNO3 yields H(+) + NO3(-). If you’re looking at strength from a pH lens (pH = -log[H+]) then equal amounts of H2SO4 and HNO3 yield [H+} 2x higher in H2SO4. Thus, Sulfuric acid has a stronger pH and is a stronger acid.
Why is nitric acid used instead of hydrochloric acid?
Nitric acid is used because all nitrate salts are soluble in water. If we use H2SO4 or HCl they will produce sulphate or chloride salts. Some metal sulphates and chlorides are not very soluble in water. Nitric acid also an oxidising agent, additioanlly breaking down the organic components better than some other acids.
Why conc Sulphuric acid is preferred over hydrochloric acid in its lab preparation?
Sulphuric acid is used for preparation of hydrogen chloride gas in laboratory. This is preferred over other acids because of the following reasons : (a) It has low volatility than HCl gas (so that the produced HCI gas is collected easily).
What is difference between hydrochloric acid and Sulphuric acid?
What is the difference between Sulphuric Acid and Hydrochloric Acid? HCl has one hydrogen atom and one chlorine atom. Sulfuric acid is H2SO4, , and has two hydrogen, one sulfur, and four oxygen atoms. Sulphuric acid is a diprotic acid whereas hydrochloric is a monoprotic acid.
What happens when hydrochloric acid reacts with Sulphuric acid?
Generally, when we add dilute hydrochloric acid to a strong (or concentrated) solution of sulfuric acid, a dehydration reaction takes place. In this reaction, the sulfuric acid strips the hydrochloric acid of its water, effectively converting it to hydrochloric acid gas.
Why is hydrochloric acid said to be a strong acid?
HCl is a strong acid because it dissociates almost completely. By contrast, a weak acid like acetic acid (CH3COOH) does not dissociate well in water – many H+ ions remain bound-up within the molecule.
Why is sulphuric acid a reducing agent?
Due to the presence of a lone pair of electrons on the sulphur atom, sulphurous acid can be easily oxidised to sulpphuric acid. Therefore, it acts as a reducing agent.
Why is sulfuric acid used as a catalyst?
Concentrated sulfuric acid is used as a catalyst, and has a dual role: Speeds up the reaction. Acts as a dehydrating agent, forcing the equilibrium to the right and resulting in a greater yield of ester.
